Subject: async_tx: rename zero_sum to val

'zero_sum' does not properly describe the operation of generating parity
and checking that it validates against an existing buffer.  Change the
name of the operation to 'val' (for 'validate').  This is in
anticipation of the p+q case where it is a requirement to identify the
target parity buffers separately from the source buffers, because the
target parity buffers will not have corresponding pq coefficients.

Subject: linker script: throw away .discard section

x86 throws away .discard section but no other archs do.  Also,
.discard is not thrown away while linking modules.  Make every arch
and module linking throw it away.  This will be used to define dummy
variables for percpu declarations and definitions.

This patch is based on Ivan Kokshaysky's alpha percpu patch.

[ Impact: always throw away everything in .discard ]

Subject: [ARM] 5574/1: ep93xx: gpio.c: fix header includes and __iomem
 pointers

Fix ep93xx gpio.c header includes and __iomem pointers.

  1. <linux/gpio.h> should be included instead of <asm/gpio.h>
  2. <mach/hardware.h> should be included instead of <mach/ep93xx-regs.h>
  3. data_reg and data_dir_reg in struct ep93xx_gpio_chip should be
     void __iomem pointers not unsigned int

ep93xx: Show gpio interrupt type in debugfs output.

EP93xx uses a private implementation for the debugfs output.
Modify this output so it includes the interrupt type when the
gpio is configured as an interrupt

Subject: [ARM] 5566/1: Remove at91_gpiolib_request

Remove at91_gpiolib_request. It returns -EPERM if a request pin is not
in GPIO mode, however we want to be able to gpio_request alternative
function pins to reserve them, and in some cases we need to be able to
use the gpiolib functions on alternative function pins.

Subject: [ARM] 5569/1: at91: Support for at91sam9g45: clocks management

Add the at91sam9g45 series support to the AT91 generic clock file.
This takes care of the particularities of the PMC for this series.
It also takes advantage of the management by functionalities of
those PLLs and clocks.

From 789b23bc40a67d9a19bedc2655c6bcab79bcabd8 Mon Sep 17 00:00:00 2001
From: Nicolas Ferre <nicolas.ferre@atmel.com>
Date: Fri, 26 Jun 2009 15:36:58 +0100
Subject: [ARM] 5572/1: at91: Support for at91sam9g45 series: core chip & board
 support

Here are the at91 specific files dedicated to the at91sam9g45 series. They
mimic the traditional at91 way of managing chips & boards.

The first board that embeds at91sam9g45 chip is the AT91SAM9G45-EKES. In
the future, the main board for this 9g45 series will be the
AT91SAM9M10G45-EK (I choose this last name for the board file).

Simple drivers are enabled in _devices and board- files. Newer peripheral
support will be added in future patches.

Incuded peripherals support (for now):
- USART
- SPI
- Ethernet
- NAND flash
- LCD
- gpio/joystick/buttons
- leds and pwm

Subject: [ARM] 5582/1: VIC: support ST-modified version with a split init

The Nomadik SoC (not yet merged) has a modified PL090 VIC cell. This adds
support for it by reading the PrimeCell ID at the end of the page and
calling a separate init function.

Subject: [ARM] 5583/1: VIC: acknowledge software interrupts

The PrimeCell Vectored Interrupt Controller offers a way to trigger
any interrupt through software. This is a useful tool for developing,
but such software interrupt can only be acked by writing a bit in the
"software clear" register, or the handler will loop forever.  This
splits ack from mask, and acks the soft irq in case it was the source.

This patch adds the basic infrastructure for the Nomadik 8815
CPU and the "Nomadik Hardware Kit" NHK8815. This patch only
includes the serial console and core stuff, no drivers.

From 7fb2bbf4d9e7e62057184f1e061566459eef6c79 Mon Sep 17 00:00:00 2001
From: Russell King <rmk@dyn-67.arm.linux.org.uk>
Date: Thu, 9 Jul 2009 15:15:12 +0100
Subject: MMC: MMCI: allow GPIOs to be passed

Add and initialize the gpio_wp and gpio_cd members.  We need to
ensure that all users are covered, because GPIO 0 may be valid.

Subject: [ARM] 5577/2: ep93xx: syscon locked register functions

Add core functions to handle writes to the ep93xx software locked
registers.

There are a number of registers in the EP93xx System Controller
that require a write to the software lock register before they
can be updated. This patch adds a number of exported functions
to the ep93xx core that handle this access.

The software locked clock divider registers, VidClkDiv, MIRClkDiv,
I2SClkDiv and KeyTchClkDiv would typically involve writing a
specific value to the register. To support this the
ep93xx_syscon_swlocked_write() function is provided.

For the DeviceCfg register it's more typical to only need to
set or clear a single bit. A generic ep93xx_devcfg_set_clear()
function is provided to handle both operations. Two inline
functions, ep93xx_devcfg_set_bits() and ep93xx_devcfg_clear_bits()
are also provided to improve code readability.

In addition, the remaining bits in the System Controller Device
Config Register have been documented and the previously defined
names shortened.

All code paths that use this functionality have been updated
except for arch/arm/kernel/crunch.c. That code is in a context
switch path, which is not reentrant, so it is safe against itself.

Subject: [ARM] 5578/1: ep93xx: add ep93xx-keypad clock

Add clkdev support for the ep93xx_keypad driver.

A matrix keypad driver for the ep93xx just got merged via the
input subsystem group.  For this driver to work the keypad clock
needs to be added to the ep93xx clkdev support.  In order to
accomplish this the following changes are implemented:

  1) Move the EP93XX_EXT_*_RATE defines to mach/include/hardware.h.
  2) Add EP93XX_KEYTCHCLK_DIV{4/16} for the keypad driver.
  3) Add support for programmable clocks (set_rate() callback).
  4) Add clk_keypad for the keypad driver.
  5) tab indent the clk_lookup table for easier reading.
  6) Add the set_rate() callback to program the keypad clock.
     This callback is generalized since the ADC clock (touchscreen)
     can use the same callback.
  7) Use the ep93xx_syscon_swlocked_write() core function for updating
     the software locked register.

From 583ddafe1787528d08b0026bb3273490a499b730 Mon Sep 17 00:00:00 2001
From: Hartley Sweeten <hartleys@visionengravers.com>
Date: Mon, 6 Jul 2009 17:39:50 +0100
Subject: [ARM] 5592/1: ep93xx: cleanup platform header includes

arch/arm/mach-ep93xx/include/mach/hardware.h
  1. Properly name the include files so that they are loaded
     from the <mach/*> directory and not the local directory.
  2. Remove including the ts72xx.h header.  This header is not
     generic to the ep93xx platform.  It should only be included
     by the ts72xx specific files that require it.  The only
     two users in the tree are arch/arm/mach-ep93xx/ts72xx.c
     and drivers/mtd/nand/ts7250.c.

arch/arm/mach-ep93xx/include/mach/ts72xx.h
  1. <linux/io.h> should already be included by any user of this
     header.  Doing the include here hides it from being needed
     by the calling source file.

arch/arm/mach-ep93xx/core.c
  1. Remove unnecessary headers.  They were probably included
     originally due to cut-and-paste from other files.
  2. <linux/io.h> should be included not <mach/gpio.h>

arch/arm/mach-ep93xx/adsphere.c
arch/arm/mach-ep93xx/edb93xx.c
arch/arm/mach-ep93xx/gesbc9312.c
arch/arm/mach-ep93xx/micro9.c
arch/arm/mach-ep93xx/ts72xx.c
  1. Remove unnecessary headers.

arch/arm/mach-ep93xx/ts72xx.c
  1. Remove unnecessary headers.
  2. Add platform specific header <mach/ts72xx.h>.

drivers/mtd/nand/ts7250.c
  1. <linux/io.h> should be included not <asm/io.h>.
  2. Add platform specific header <mach/ts72xx.h>.

Subject: [ARM] 5596/1: at91sam9g20-ek: Register WM8731 in board file

The WM8731 driver has been updated to allow registration via normal
device model methods rather than from within the ASoC driver probe
so update the AT91SAM9G20-EK to make use of this.

These old symbols are meaningless now that we have memory type
support implemented.  The entire memory type field needs to be
modified rather than just a few bits twiddled.

Subject: [ARM] pgtable: rearrange file PTE bit allocation

For future compatibility, we need to ensure that swap and file Linux
PTEs conform with the hardware PTEs "fault" encoding.  Swap PTEs
already fit in with this, but file PTEs do not.  Shift them by one
bit to ensure that they conform, using bit 2 to distinguish between
swap and file PTEs.

Subject: [ARM] 5600/1: ep93xx: core.c remove cast when copying dev_addr

The MAC address for the ep93xx ethernet driver can be optionally
copied from registers in the controller when booting.  Due to
[ARM] 5573/1: ep93xx: ensure typesafe io, the cast for the source
address is no longer needed.

EP93XX_ETHERNET_BASE is typed as a (void __iomem __force *) so
memcpy_fromio() needs to be used instead of memcpy().

Subject: ARM: S3C: Update hwmon device definition and name

Change the hwmon device name to something more generic as this
should be functional for both the s3c24xx and s3c64xx archs.

Since it has yet to have a driver, it is pretty safe to change
as there are no extant users.

Also add the necessary entry in devs.h which seems to have been
missed  out at somepoint.

Subject: [ARM] 5612/1: ep93xx: add platform LEDs

The EP93xx has two gpio pins specifically assigned to drive
external LEDs.  Add core support for these LEDs.

On the EDB93xx development boards, the rdled is connected to
an external reset circuit.  Turning this led on for an extended
amount of time will cause the circuit to issue a manual reset.

Refer to Cirrus App Note AN258 for more information.

	http://www.cirrus.com/en/pubs/appNote/AN258REV2.pdf

This led can be safely used as the system heartbeat with the
ledtrig-heartbeat driver.

	echo heartbeat > /sys/class/leds/platform:rdled/trigger

The grled can be used for any desired purpose.

Subject: [ARM] 5613/1: implement CALLER_ADDRESSx
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

As __builtin_return_address(n) doesn't work for ARM with n > 0, the
kernel needs its own implementation.

This fixes many warnings saying:

	warning: unsupported argument to '__builtin_return_address'

The new methods and walk_stackframe must not be instrumented because
CALLER_ADDRESSx is used in the various tracers and tracing the tracer is
a bad idea.

What's currently missing is an implementation using unwind tables.  This
is not fatal though, it's just that the tracers don't get enough
information to be really useful.

Note that if both ARM_UNWIND and FRAME_POINTER are enabled,
walk_stackframe uses unwind information.  So in this case the same
implementation is used as when FRAME_POINTER is disabled.

Subject: Driver Core: Add platform device arch data V3

Allow architecture specific data in struct platform_device V3.

With this patch struct pdev_archdata is added to struct
platform_device, similar to struct dev_archdata in found in
struct device. Useful for architecture code that needs to
keep extra data associated with each platform device.

Struct pdev_archdata is different from dev.platform_data, the
convention is that dev.platform_data points to driver-specific
data. It may or may not be required by the driver. The format
of this depends on driver but is the same across architectures.

The structure pdev_archdata is a place for architecture specific
data. This data is handled by architecture specific code (for
example runtime PM), and since it is architecture specific it
should _never_ be touched by device driver code. Exactly like
struct dev_archdata but for platform devices.

[rjw: This change is for power management mostly and that's why it
 goes through the suspend tree.]

Subject: Thumb-2: Add some .align statements to the .S files

Since the Thumb-2 instructions can be 16-bit wide, data in the .text
sections may not be aligned to a 32-bit word and this leads to unaligned
exceptions. This patch does not affect the ARM code generation.

Subject: Thumb-2: Add support for loadable modules

Modules compiled to Thumb-2 have two additional relocations needing to
be resolved at load time, R_ARM_THM_CALL and R_ARM_THM_JUMP24, for BL
and B.W instructions. The maximum Thumb-2 addressing range is +/-2^24
(+/-16MB) therefore the MODULES_VADDR macro in asm/memory.h is set to
(MODULES_END - 8MB) for the Thumb-2 compiled kernel.

Subject: nommu: ptrace support

The patch below adds ARM ptrace functions to get the process load address.
This is required for useful userspace debugging on mmuless systems.  These
values are obtained by reading magic offsets with PTRACE_PEEKUSR, as on other
nommu targets. I picked arbitrary large values for the offsets.

From ef12379f205bed7e92434e12ddd44e62d13bebe1 Mon Sep 17 00:00:00 2001
From: Hartley Sweeten <hartleys@visionengravers.com>
Date: Wed, 29 Jul 2009 22:41:06 +0100
Subject: ARM: 5628/1: ep93xx: Introduce Pulse Width Modulator (PWM) driver

The EP93xx features two PWMs (one on the EP9307) with the following
features:

  * Configurable dual output
  * Separate input clocks for each PWM output
  * 16-bit resolution
  * Programmable pulse width (duty cycle), interval (frequency), and
    polarity

This adds the necessary core support as well as the driver.  A sysfs
interface is provided to control the PWM outputs.

From e13cf03eaae3792442c401860910d40f33c89a33 Mon Sep 17 00:00:00 2001
From: Ben Dooks <ben@simtec.co.uk>
Date: Thu, 30 Jul 2009 23:23:35 +0100
Subject: ARM: S3C: Update CPU register mapping practices.

Currently map-base.h defines the main virtual address mappings made
for all the support S3C SoC series, but does not then define any base
for per-cpu mappings to be made from.

Add S3C_ADDR_CPU() macro to define an virtual address as an offset
from the last of the core mappings.

Subject: ARM: S3C2410: Add S3C2410A sysdev.

Add a sysdev S3C2410A sysdev to allow the differentiation
of the S3C2410A from the S3C2410. This is needed for the
CPUFREQ code to enable the extra features and update cpu
specific information.

Subject: ARM: S3C: move s3c_device_nand from plat-s3c24xx to plat-s3c

Move the s3c_device_nand platform device from plat-s3c24xx to plat-s3c,
now that the nand driver also support the s3c64xx devices.

Subject: ARM: S3C: move timer/pwm handling from plat-s3c24xx to plat-s3c

The s3c64xx devices use the same hardware core as s3c24xx, so move
the timer/pwm handling to plat-s3c so it can be used by both.

Subject: ARM: 5635/1: Use DIV_ROUND_CLOSEST

The kernel.h macro DIV_ROUND_CLOSEST performs the computation
(x + d/2)/d but is perhaps more readable.

The semantic patch that makes this change is as follows:

Subject: ¶ARM] Orion5x: fix cpu window mapping for 88f6183
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On the 88f6183, orion5x's setup_cpu_win() fails to ever program any
mbus bridge remap registers, which causes transactions for PCI/PCIe
IO/MEM space to get sent to random mbus targets.  Adding a check for
the 6183 in orion5x_cpu_win_can_remap() is necessary and sufficient
to make PCIe wlan cards work on the 6183 reference design.

Subject: netx: Use get_irqnr_preamble to initialize base register
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch optimizes the irq handling a bit.  Now the base register is
only computed once per irq exception instead of at least twice.
Moreover the mov+add sequence is simplified to an ldr (which might save
some cycles depending on memory timing).

Before this patch enabling and disabling irqs in assembler code and by

I had to transpose two instructions in arch/arm/lib/bitops.h because
restore_irqs doesn't preserve the flags with CONFIG_TRACE_IRQFLAGS=y

Subject: Use kernel/Kconfig.preempt for ARM
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

before this patch ARM had it's own definition of CONFIG_PREEMPT.
Instead of that use the general definition provided in
kernel/Kconfig.preempt.

This patch changes the available options in *config.  Namely PREEMPT
isn't a stand alone bool anymore, but part of a 'choice' the
following Kconfig symbols are added:

	PREEMPT_NONE
	PREEMPT_VOLUNTARY

Selecting PREEMPT_NONE now produces exactly the code as not selecting
PREEMPT before (apart from a comment in
/sys/kernel/debug/tracing/(per_cpu/cpuX/)?trace).  The only difference
PREEMPT_VOLUNTARY does is that might_resched might reschedule.  Both
should't introduce regressions.

Subject: [ARM] let arch/arm/Kconfig source drivers/Kconfig
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The changes introduced by this change are:
  - drivers/mtd/Kconfig doesn't depend on ALIGNMENT_TRAP ||
    !CPU_CP15_MMU any more
  - the following files are sourced additionally:
    + drivers/macintosh/Kconfig
      completely depends on PPC || MAC || X86
    + drivers/telephony/Kconfig
      new
    + drivers/pps/Kconfig
      new
    + drivers/infiniband/Kconfig
      new
    + drivers/edac/Kconfig
      depends on X86 || PPC
    + drivers/vlynq/Kconfig
      depends on AR7 && EXPERIMENTAL (that is ARCH_MIPS)
    + drivers/xen/Kconfig
      everything depends on XEN
    + drivers/platform/Kconfig
      depends on X86
  - drivers/regulator/Kconfig is sourced later as is
    drivers/accessibility/Kconfig

Subject: ARM: S3C24XX: Add FIQ IRQ routing support

Add support for routing an IRQ from the normal ARM IRQ mechanism to the
FIQ input of the processor.

Note, also fix a bug where the init_FIQ() function has not been called
when CONFIG_FIQ is enabled.

Subject: timekeeping: Move NTP adjusted clock multiplier to struct timekeeper

The clocksource structure has two multipliers, the unmodified multiplier
clock->mult_orig and the NTP corrected multiplier clock->mult. The NTP
multiplier is misplaced in the struct clocksource, this is private
information of the timekeeping code. Add the mult field to the struct
timekeeper to contain the NTP corrected value, keep the unmodifed
multiplier in clock->mult and remove clock->mult_orig.

Subject: ARM: 5677/1: ARM support for
 TIF_RESTORE_SIGMASK/pselect6/ppoll/epoll_pwait

This patch adds support for TIF_RESTORE_SIGMASK to ARM's
signal handling, which allows to hook up the pselect6, ppoll,
and epoll_pwait syscalls on ARM.

Tested here with eabi userspace and a test program with a
deliberate race between a child's exit and the parent's
sigprocmask/select sequence. Using sys_pselect6() instead
of sigprocmask/select reliably prevents the race.

The other arch's support for TIF_RESTORE_SIGMASK has evolved
over time:

In 2.6.16:
- add TIF_RESTORE_SIGMASK which parallels TIF_SIGPENDING
- test both when checking for pending signal [changed later]
- reimplement sys_sigsuspend() to use current->saved_sigmask,
  TIF_RESTORE_SIGMASK [changed later], and -ERESTARTNOHAND;
  ditto for sys_rt_sigsuspend(), but drop private code and
  use common code via __ARCH_WANT_SYS_RT_SIGSUSPEND;
- there are now no "extra" calls to do_signal() so its oldset
  parameter is always &current->blocked so need not be passed,
  also its return value is changed to void
- change handle_signal() to return 0/-errno
- change do_signal() to honor TIF_RESTORE_SIGMASK:
  + get oldset from current->saved_sigmask if TIF_RESTORE_SIGMASK
    is set
  + if handle_signal() was successful then clear TIF_RESTORE_SIGMASK
  + if no signal was delivered and TIF_RESTORE_SIGMASK is set then
    clear it and restore the sigmask
- hook up sys_pselect6() and sys_ppoll()

In 2.6.19:
- hook up sys_epoll_pwait()

In 2.6.26:
- allow archs to override how TIF_RESTORE_SIGMASK is implemented;
  default set_restore_sigmask() sets both TIF_RESTORE_SIGMASK and
  TIF_SIGPENDING; archs need now just test TIF_SIGPENDING again
  when checking for pending signal work; some archs now implement
  TIF_RESTORE_SIGMASK as a secondary/non-atomic thread flag bit
- call set_restore_sigmask() in sys_sigsuspend() instead of setting
  TIF_RESTORE_SIGMASK

In 2.6.29-rc:
- kill sys_pselect7() which no arch wanted

So for 2.6.31-rc6/ARM this patch does the following:
- Add TIF_RESTORE_SIGMASK. Use the generic set_restore_sigmask()
  which sets both TIF_SIGPENDING and TIF_RESTORE_SIGMASK, so
  TIF_RESTORE_SIGMASK need not claim one of the scarce low thread
  flags, and existing TIF_SIGPENDING and _TIF_WORK_MASK tests need
  not be extended for TIF_RESTORE_SIGMASK.
- sys_sigsuspend() is reimplemented to use current->saved_sigmask
  and set_restore_sigmask(), making it identical to most other archs
- The private code for sys_rt_sigsuspend() is removed, instead
  generic code supplies it via __ARCH_WANT_SYS_RT_SIGSUSPEND.
- sys_sigsuspend() and sys_rt_sigsuspend() no longer need a pt_regs
  parameter, so their assembly code wrappers are removed.
- handle_signal() is changed to return 0 on success or -errno.
- The oldset parameter to do_signal() is now redundant and removed,
  and the return value is now also redundant and changed to void.
- do_signal() is changed to honor TIF_RESTORE_SIGMASK:
  + get oldset from current->saved_sigmask if TIF_RESTORE_SIGMASK
    is set
  + if handle_signal() was successful then clear TIF_RESTORE_SIGMASK
  + if no signal was delivered and TIF_RESTORE_SIGMASK is set then
    clear it and restore the sigmask
- Hook up sys_pselect6, sys_ppoll, and sys_epoll_pwait.

Subject: ARM: S5PC100: Memory map

S5PC100's the physical IO space starts at 0xe000"0000. To maximize space for
vmalloc, the virtual IO space starts at 0xf400"0000 as same as other samsung
CPUs(s3c24xx and s3c64xx) do.

Subject: ARM: S5PC100: UART and Serial

Serial driver of S5PC100 is the same as S3C6400, so S5PC100 shares the serial
driver with S3C6400. Uart driver is copied from plat-s3c64xx to plat-s5pc1xx,
as I do not use plat-s3c64xx directory.

Subject: ARM: S5PC100: IRQ and timer

S5PC100 has 3 VICs(Vectored Interrupt Controller). The VICs come from S3C64xx
series, so the driver source code can be shared with S3C families. The S5PC100
has 3 VICs while S3C64xx has only 2.

Subject: ARM: S5PC100: Kconfigs and Makefiles

S5PC100 is a new SoC with ARM coretex-A8 and numerous peripherals. This SoC is
successor of S3C64XX. S5PC100 has peripherals which are still similar to S3C
families so some drivers in "arch/arm/plat-s3c" can be shared. S5PC100 specific
drivers will be added in "arch/arm/plat-s5pcxx" or "arch/arm/mach-s5pc100"

Subject: ARM: S3C: Add S3C_DEV_NAND Kconfig entry

Currently the S5PC100 does not define S3C_PA_NAND, leaving the NAND device
definitions in arch/arm/plat-s3c/dev-nand.c unbuildable. Add a KConfig
entry to select whether this is built.

As backwards compatibility, both the S3C24XX and S3C64XX define the new
configuration in their main Kconfig files until better support for basing
this selection on a per-machine basis can be sorted out.

Subject: ARM: Show FIQ in /proc/interrupts on CONFIG_FIQ

The show_fiq_list() call in arch/arm/kernel/irq.c currently depends on
CONFIG_ARCH_ACORN, but this is not the only architecture that supports
the usage of FIQ. Change to calling this if CONFIG_FIQ is set (which
is what arch/arm/kernel/fiq.c is built by).

Subject: davinci: EDMA: multiple CCs, channel mapping and API changes

- restructure to support multiple channel controllers by using
  additional struct resources for each CC

- interface changes visible to EDMA clients

  Introduce macros to build IDs from controller and channel number,
  and to extract them. Modify the edma_alloc_slot function to take an
  extra argument for the controller.

  Also update ASoC drivers to use API.  ASoC changes
  Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

- Move queue related mappings to dm<soc>.c

  EDMA in DM355 and DM644x has two transfer controllers while DM646x
  has four transfer controllers. Moving the queue to tc mapping and
  queue priority mapping to dm<soc>.c will be helpful to probe these
  mappings from platform device so that the machine_is_* testing will
  be avoided.

- add channel mapping logic

  Channel mapping logic is introduced in dm646x EDMA. This implies
  that there is no fixed association for a channel number to a
  parameter entry number. In other words, using the DMA channel
  mapping registers (DCHMAPn), a PaRAM entry can be mapped to any
  channel. While in the case of dm644x and dm355 there is a fixed
  mapping between the EDMA channel and Param entry number.

Subject: davinci: Fix watchdog reset code

The davinci reset routine, davinci_watchdog_reset(), sets the
TCR register instead of the TGCR register as it should to put
the WDT into its "Initial State".

It also writes the WDTCR register without the proper WDKEY
which is pointless since the register will be write-protected.

Subject: davinci: dm365 evm cpld support: leds, card detect, other setup

Add basic support for the CPLD on the DM365 EVM board:

 - Read SW5 to set up NAND and keypad vs (someday) OneNAND
 - Export MMC/SD card detect and writeprotect signals
 - LED support (same layout as on DM355 EVM)
 - Static config for video input:
     * external HD imager precludes MMC1, Ethernet, audio
     * else either tvp5146 (SD/default) or tvp7002 (HD)

The video input could actually be switched around dynamically;
change that if/when that's needed (and after those other video
inputs have driver support).

Subject: davinci: da8xx: Add base DA830/OMAP-L137 SoC support

The da830/omap l137 is a new SoC from TI that is similar
to the davinci line.  Since its so similar to davinci,
put the support for the da830 in the same directory as
the davinci code.

There are differences, however.  Some of those differences
prevent support for davinci and da830 platforms to work
in the same kernel binary.  Those differences are:

1) Different physical address for RAM.  This is relevant
   to Makefile.boot addresses and PHYS_OFFSET.  The
   Makefile.boot issue isn't truly a kernel issue but
   it means u-boot won't work with a uImage including
   both architectures.  The PHYS_OFFSET issue is
   addressed by the "Allow for runtime-determined
   PHYS_OFFSET" patch by Lennert Buytenhek but it
   hasn't been accepted yet.

2) Different uart addresses.  This is only an issue
   for the 'addruart' assembly macro when CONFIG_DEBUG_LL
   is enabled.  Since the code in that macro is called
   so early (e.g., by _error_p in kernel/head.S when
   the processor lookup fails), we can't determine what
   platform the kernel is running on at runtime to use
   the correct uart address.

These areas have compile errors intentionally inserted
to indicate to the builder they're doing something wrong.

A new config variable, CONFIG_ARCH_DAVINCI_DMx, is added
to distinguish between a true davinci architecture and
the da830 architecture.

Note that the da830 currently has an issue with writeback
data cache so CONFIG_CPU_DCACHE_WRITETHROUGH should be
enabled when building a da830 kernel.

Additional generalizations for future SoCs in the da8xx family done by
Sudhakar Rajashekhara and Sekhar Nori.

From 8593790d604c29a717d5914159ce78c7bb9899fb Mon Sep 17 00:00:00 2001
From: "Mark A. Greer" <mgreer@mvista.com>
Date: Wed, 3 Jun 2009 18:41:53 -0700
Subject: davinci: da8xx: Add support for DA830/OMAP-L137 EVM board

Add support for the DA830/OMAP-L137 Evaluation Module (EVM)
from TI.  The EVM has User Interface (UI) and Audio cards
that can be connected which contain various devices.
Support for those devices and ones on the EVM will be
added in subsequent patches.

Additional generalizations for future SoCs in da8xx family done by
Sudhakar Rajashekhara and Sekhar Nori.

Subject: davinci: dm365 gpio irq support

Support DM365 GPIOs ... primarily by handling non-banked GPIO IRQs:

 - Flag DM365 chips as using non-banked GPIO interrupts, using a
   new soc_info field.

 - Replace the gpio_to_irq() mapping logic.  This now uses some
   runtime infrastructure, keyed off that new soc_info field,
   which doesn't handle irq_to_gpio().

 - Provide a new irq_chip ... GPIO IRQs handled directly by AINTC
   still need edge triggering managed by the GPIO controller.

DM365 chips no longer falsely report 104 GPIO IRQs as they boot.

Intelligence about IRQ muxing is missing, so for the moment this
only exposes the first eight DM365 GPIOs, which are never muxed.
The next eight are muxed, half with Ethernet (which uses most of
those pins anyway).

Tested on DM355 (10 unbanked IRQs _or_ 104 banked ones) and also
on DM365 (16 unbanked ones, only 8 made available).

Subject: davinci: ASoC: Add the platform devices for ASP

1) Registers the platform devices for ASP on dm355, dm644x and dm646x
   so that the machine driver can probe to get ASP related platform
   data.
2) Move towards definition of the asp clocks using physical name(for
   dm355 and dm644x)
3) Add platform data to board specific files.

Subject: davinci: Move IO device mapping macros from io.h to hardware.h

This patch takes out IO mapping macros from mach/io.h and puts them in
mach/hardware.h avoiding need to include mach/io.h in various files such as
serial.h, vmalloc.h etc.

The main reason to avoid inclusion of mach/io.h is, when default in/out macros
are overridden by machine specific functions (e.g., in case of PCI I/O), they
result into linker error. An example snippet and error snapshot is listed below.

Following code in mach/io.h:

	#define inl(p)  my_inl()

	static inline unsigned int my_inl(unsigned int addr)
	{
		if (IS_PCI_IO(addr))
			return pci_inl ();
		else
			return le32_to_cpu(__raw_readl(__typesafe_io(addr)));
	}

leads to error:
	LD      arch/arm/boot/compressed/vmlinux
	arch/arm/boot/compressed/misc.o: In function `my_inl':
	misc.c:(.text+0x2744): undefined reference to `pci_inl'
	make[2]: *** [arch/arm/boot/compressed/vmlinux] Error 1

This is because mach/io.h gets included in arch/arm/boot/compressed/misc.c
through mach/serial.h but pci.c file, which defines 'pci_inl' doesn't get built
into compressed vmlinux.

Subject: davinci: make arch_idle and arch_reset as inline functions

Make arch_idle and arch_reset inline as inline function.

Not having them inline leads to a warning of this sort when only
one of these functions is used:

arch/arm/mach-davinci/include/mach/system.h:24: warning: 'arch_reset' \
defined but not used

boot, re-boot tested on OMAP-L138 EVM

Subject: davinci: dm646x: Add IDE setup

This patch adds platform data and init function for IDE which could be called
from board specific file to register IDE device.

Note that for 594MHz device the transfer mode is limited to UDMA4 since ideclk
rate is less than 100 MHz, which forces udma_mask in palm_bk3710.c to UDMA4,
while for 729MHz device, it is UDMA5.

Subject: davinci: Move the da830/omap-l137 #defines to header file

With the introduction of TI da850/omap-l138, some of the macros
defined for da830/omap-l137 will be needed in da850 source file.
So, move the common macros to da8xx.h header file.

Also, modify the macro names from DA830_... to DA8XX_.

Subject: davinci: Add base DA850/OMAP-L138 SoC support

The DA850/OMAP-L138 is a new SoC from TI in the same family as
DA830/OMAP-L137.

Major changes include better support for power management,
support for SATA devices and McBSP (same IP as DM644x).

DA850/OMAP-L138 documents are available at
http://focus.ti.com/docs/prod/folders/print/omap-l138.html.

From 0fbc5592158db4e1ca2037178e1ea6733ccc6f61 Mon Sep 17 00:00:00 2001
From: Sudhakar Rajashekhara <sudhakar.raj@ti.com>

Subject: davinci: Add support for DA850/OMAP-L138 EVM board

Add support for the DA850/OMAP-L138 Evaluation Module (EVM)
from TI.  The EVM has User Interface (UI) card which contains
various devices. This UI card can be connected to the base
board. Support for all the devices on the UI card and ones on
the EVM will be added in subsequent patches.

The EVM schematics are not available publicly yet; but should
be available soon.

A new defconfig for this board has been added mainly because
the DA830/OMAP-L137 defconfig forces writethrough cache mode
which is not required on DA850/OMAP-L138.

This patch has been boot tested on DA850/OMAP-L138 EVM
using ramdisk as filesystem.

Subject: davinci: Add EMAC support for da850/omap-l138

Ethernet Media Access Controller (EMAC) on da850/omap-l138
supports 10/100 Mbps operation. It also supports Media
Independent Interface (MII) and Reduced Media Independent
Interface (RMII) to physical layer (PHY).

Phy which supports MII is present on the DA850/OMAP-L138
base board and Phy supporting RMII is present on the
UI card. This patch adds support only for the MII Phy.
Support for RMII Phy will be added later.

Subject: DaVinci: EDMA: Updating default queue handling

EDMA queues in DM365 are a little different than those
on other DaVinci's. On DM365 Q0 and Q1 have the larger
FIFO size. We want Q0 and Q1 to be used by codecs and
DVSDK demos.
MMC driver is the only driver which uses the flag
'EVENTQ_DEFAULT'. So MMC driver should be using Q2 instead of
Q1 on DM365.
This patch allows us to declare a "default queue" from
SOC specific code. If it is not declared then the EDMA
driver assumes a default of queue 1.

Subject: davinci: Configure MDIO pins for EMAC

Earlier patch which adds EMAC support for da850/omap-l138
was not configuring the MDIO pins.

Ethernet was working fine with the earlier patch, because
the MDIO pins were configured from the boot loader. This
patch removes that dependency.

Also, this patch populates a member in the emac clk structure
to say that EMAC LPSC sits on controller 1.

Subject: davinci: Add MMC/SD support for da850/omap-l138

There are two instances of MMC/SD on da850/omap-l138.
Connector for the first instance is available on the
EVM. This patch adds support for this instance.

This patch also adds support for card detect and write
protect switches on da850/omap-l138 EVM.

Subject: davinci: Add NOR flash support for da850/omap-l138

This patch adds platform data for the 8MB NOR flash
found on da850/omap-l138 EVM. Both NOR and NAND can
co-exist on da850/omap-l138 as they are using different
chip selects.

Subject: davinci: Handle pinmux conflict between mmc/sd and nor flash

On DA850/OMAP-L138 EVM, MMC/SD and NOR Flash share
some of the AEMIF pins. This patch prints out a warning
during booting, if both MMC/SD and NOR Flash are enabled
in kernel menuconfig.

If both MMC/SD and NOR Flash are enabled, only MMC/SD
will work correctly.

Subject: DaVinci: DM365: Adding entries for DM365 IRQ's

This patch adds definitions for some DM365 IRQs that are used by
the codecs. Codecs will also use the IRQs.
Entries are being added to enable/disable IRQ's.
There is no use as such for these entires in the kernel itself.
Instead these will be used by the "linuxutils" package of the DVSDK.

For further information on IRQ muxing refer to

is most efficient if they are contiguous.
There is an API to allocate a set of contiguous parameter RAMs and
a corresponding API to free a set of contiguous parameter RAMs

Subject: OMAP: Remove OMAP_IO_ADDRESS, use OMAP1_IO_ADDRESS and
 OMAP2_IO_ADDRESS instead

Search and replace OMAP_IO_ADDRESS with OMAP1_IO_ADDRESS and OMAP2_IO_ADDRESS,
and convert omap_read/write into a functions instead of a macros.

Also rename OMAP_MPUIO_VBASE to OMAP1_MPUIO_VBASE.

In the long run, most code should use ioremap + __raw_read/write instead.

Subject: OMAP: UART: drop OMAP_TAG_UART, enable all UARTs, auto-disabled on
 idle

OMAP tags are deprecrated so drop them.

Drop UART config data which decides which UARTs to enable during boot.
This is no longer necessary since serial core code disables clocks
after inactivity.

Background: with new UART idle code, all on-chip UARTs are idled using
a configurable inactivity timer (default 5 seconds.)  After the
inactivity timer, UART clocks are disabled automatically.

Subject: OMAP: GPIO: Avoid generating extra IRQs

It is possible for GPIO IRQ lines configured with
falling edge triggering only to get IRQs at the
rising edge upon the exit of offmode. And vice
versa. Prevent such IRQs to arrive by generating
the IRQ obeying the detection scheme.

Subject: OMAP1: AMS_DELTA: add modem support

This patch adds support for modem device found on Amstrad E3 (Delta) board.

Based on earlier patch by Jonathan McDowell, available at
http://the.earth.li/pub/e3/2.6.19/ams-delta-modem.patch.
Modified after Ladislav Michl's arch/arm/mach-omap1/board-voiceblue.c.

This patch is dependent on 8250 driver changes getting accepted upstream:
http://git.kernel.org/?p=linux/kernel/git/sfr/linux-next.git;a=commit;h=7053133124d5cdf207c1168c7a0c582a18e12ea7

Subject: OMAP: iommu: fix wrong argument in flush_cache_vmap()

The second argument should be the end address, not the
length. Actually there will not be any effect on the behavior of this
driver since flush_cache_vmap() calls flush_cache_all() in the end.

Subject: OMAP2/3: Pass irqflags to 8250 driver

Pass irqflags to 8250 driver with platform_data. At least Zoom2 has
IRQF_TRIGGER_RISING requirement for the 8250 GPIO irq.

This patch is dependent on 8250 driver changes getting accepted upstream:

Subject: OMAP3: 3430SDP: Fix defconfig

This patch makes the SDP boot again with the defconfig.

Changes done:

 - Removes other selected boards.
 - Sets the Low Level debug output for UART1.
 - Disables some paripherals from other boards.

Tested on a SDP3430-VE5.1.0 (OMAP3430 ES3.1)

Subject: OMAP3: update OMAP3 Beagle defconfig

Update the OMAP3 Beagle defconfig to add EHCI, MMC, TWL4030 GPIO support.
Beagle can again use MMC rootfs after this patch.  Tested on BeagleBoard
rev C2.

Patch updated to enable PM and OTG options as suggested by
Eric Witcher <ewitcher@mindspring.com>.

Subject: async_tx: add sum check flags

Replace the flat zero_sum_result with a collection of flags to contain
the P (xor) zero-sum result, and the soon to be utilized Q (raid6 reed
solomon syndrome) zero-sum result.  Use the SUM_CHECK_ namespace instead
of DMA_ since these flags will be used on non-dma-zero-sum enabled
platforms.

Subject: async_tx: add support for asynchronous GF multiplication

[ Based on an original patch by Yuri Tikhonov ]

This adds support for doing asynchronous GF multiplication by adding
two additional functions to the async_tx API:

 async_gen_syndrome() does simultaneous XOR and Galois field
    multiplication of sources.

 async_syndrome_val() validates the given source buffers against known P
    and Q values.

When a request is made to run async_pq against more than the hardware
maximum number of supported sources we need to reuse the previous
generated P and Q values as sources into the next operation.  Care must
be taken to remove Q from P' and P from Q'.  For example to perform a 5
source pq op with hardware that only supports 4 sources at a time the
following approach is taken:

p, q = PQ(src0, src1, src2, src3, COEF({01}, {02}, {04}, {08}))
p', q' = PQ(p, q, q, src4, COEF({00}, {01}, {00}, {10}))

p' = p + q + q + src4 = p + src4
q' = {00}*p + {01}*q + {00}*q + {10}*src4 = q + {10}*src4

Note: 4 is the minimum acceptable maxpq otherwise we punt to
synchronous-software path.

The DMA_PREP_CONTINUE flag indicates to the driver to reuse p and q as
sources (in the above manner) and fill the remaining slots up to maxpq
with the new sources/coefficients.

Note1: Some devices have native support for P+Q continuation and can skip
this extra work.  Devices with this capability can advertise it with
dma_set_maxpq.  It is up to each driver how to handle the
DMA_PREP_CONTINUE flag.

Note2: The api supports disabling the generation of P when generating Q,
this is ignored by the synchronous path but is implemented by some dma
devices to save unnecessary writes.  In this case the continuation
algorithm is simplified to only reuse Q as a source.

Subject: iop-adma: P+Q support for iop13xx adma engines

iop33x support is not included because that engine is a bit more awkward
to handle in that it can either be in xor mode or pq mode.  The
dmaengine/async_tx layers currently only comprehend static capabilities.

Note iop13xx does not support hardware PQ continuation so the driver
must handle the DMA_PREP_CONTINUE flag for operations across > 16
sources. From the comment for dma_maxpq:

/* When an engine does not support native continuation we need 3 extra
 * source slots to reuse P and Q with the following coefficients:
 * 1/ {00} * P : remove P from Q', but use it as a source for P'
 * 2/ {01} * Q : use Q to continue Q' calculation
 * 3/ {00} * Q : subtract Q from P' to cancel (2)
 */

Subject: ARM: 5682/1: Add cpu.c and dev.c and modify some files of w90p910
 platform

Add the cpu.c and dev.c and modify w90p910 platform
to apply to use the common API(provided by cpu.c and dev.c)
at the same time, I renamed all w90x900 to nuc900 in every
c file of w90x900 platform and touchscreen's driver name.

Subject: ARM: 5687/1: fix an oops with highmem

In xdr_partial_copy_from_skb() there is that sequence:

		kaddr = kmap_atomic(*ppage, KM_SKB_SUNRPC_DATA);
		[...]
		flush_dcache_page(*ppage);
		kunmap_atomic(kaddr, KM_SKB_SUNRPC_DATA);

Mixing flush_dcache_page() and kmap_atomic() is a bit odd,
especially since kunmap_atomic() must deal with cache issues
already.  OTOH the non-highmem case must use flush_dcache_page()
as kunmap_atomic() becomes a no op with no cache maintenance.

Problem is that with highmem the implementation of kmap_atomic()
doesn't set page->virtual, and page_address(page) returns 0 in
that case. Here flush_dcache_page() calls __flush_dcache_page()
which calls __cpuc_flush_dcache_page(page_address(page)) resulting
in a kernel oops.

None of the kmap_atomic() implementations uses set_page_address().
Hence we can assume page_address() is always expected to return 0 in
that case. Let's conditionally call __cpuc_flush_dcache_page() only
when the page address is non zero, and perform that test only when
highmem is configured.

Subject: ARM: OMAP4: Fix NULL pointer dereference crash.

After the patch series "[PATCH 00/14] OMAP PM fixes for .31-rc"
merge in 2.6.31-rc5, the kernel crashed during boot on OMAP4430.
This patch fixes it by adding UART4 support and related code.
Without this patch omap_serial_init() would produce " NULL pointer
dereference" and kernel crashes in the bootup on OMAP4430 platform.

Some more info on the merge issue can be found here.
More info- http://lkml.org/lkml/2009/8/20/192

Note: While merging this patch,"IO_ADDRESS" needs to be changed
to "OMAP2_IO_ADDRESS" if the Tony's below series is already merged in.

Subject: ARM: OMAP4: Bypass the clock check.

Second reason of OMAP4 boot failure on 2.6.31.rc6, the UART
platform data is not getting registered to kernel.
Registration was failing because of clock check failure in
omap_serial_init().
Below patch fix the same.

OMAP4 clock framework patches are still getting discussed on mailing
list so till then we need this.

Subject: MUSB: Remove usb_musb_pm_init() call

In usb_musb_pm_init, we attempt to access an MUSB register
when the i-clock may not be on, or the module is otherwise
not accessible.

We need to either:
- enable the clock before this access, or
- remove this code and move it to the bootloader, or
- enable the clock in the bootloader

If we enable the clock in the bootloader, we might as well
add the workaround in the bootloader itself. This code will
anyway be changed once hwmod is in place, so remove it for now

This allows us to boot the kernel on certain OMAP3 boards with
a bootloader that doesn't enable this clock. Without this, we
will need to upgrade the bootloaders on these boards.

Subject: OMAP3: PM: add T2 interrupt line mux setting, and enable on 3430SDP

This patch changes for setting the padconf value for sys_nirq line
which is connected to T2 INTR1.  This will fix the T2 keypad wakeup
issue on OMAP3 SDP.

Subject: OMAP3: PM: fix lockdep warning caused by omap3_pm_init

This patch uses kmalloc(size,GFP_ATOMIC) instead of kmalloc(size,GFP_KERNEL)
to allocate memory for instance of struct power_state in pwrdms_setup(),
since it may be called by pwrdm_for_each() with irq disabled.

It is a easy fix for the following lockdep warning caused by
kmalloc(size,GFP_KERNEL) in pwrdms_setup():

Power Management for TI OMAP3.

Subject: OMAP: PM counter infrastructure.

This patch provides the infrastructure to count how many times a
powerdomain entered a given power state (on, inactive, retention,
off). A number of functions are provided which will be called by the
chip specific powerdomain and clockdomain code whenever a transition
might have happened.

From 331b93f41dff21c8f95709032cb184fb82bf2003 Mon Sep 17 00:00:00 2001
From: Peter 'p2' De Schrijver <peter.de-schrijver@nokia.com>
Date: Wed, 15 Oct 2008 18:13:48 +0300
Subject: OMAP: PM: Add pm-debug counters

This patch provides the debugfs entries and a function which will be
called by the PM code to register the time spent per domain per
state. Also some new fields are added to the powerdomain struct to
keep the time information.

NOTE: As of v2.6.29, using getnstimeofday() after drivers are
suspended is no longer safe since the timekeeping subsystem is also
suspended as part of the suspend process.  Instead use sched_clock()
which on OMAP returns the 32k SYNC timer in nanoseconds.

Also, do not print out status for meta powerdomains (dpll*)

Subject: OMAP: PM debug: Add PRCM register dump support

Allows dumping out current register contents from the debug filesystem, and
also allows user to add arbitrary register save points into code. Current
register contents are available under debugfs at:

[debugfs]/pm_debug/registers/current

To add a save point, do following:

From module init (or somewhere before the save call, called only once):
  pm_dbg_init_regset(n); // n=1..4, allocates memory for dump area #n

From arbitrary code location:
  pm_dbg_regset_save(n); // n=1..4, saves registers to dump area #n

After this, the register dump can be seen under [debugfs]/pm_debug/registers/n

Subject: OMAP: powerdomain: Fix overflow when doing powerdomain deps lookups.

At the end of the list pd is a pointer to a NULL struct, so checking
if the address == NULL doesn't help here. In fact the original code
will just keep running past the struct to read who knows what in
memory.

This case manifests itself when from clkdms_setup() when enabling auto
idle for a clock domain and the clockdomain usecount is greater than
0. When _clkdm_add_autodeps() tries to add the a dependency that does
not exist in the powerdomain->wkdep_srcs array the for loop will run
past the wkdep_srcs array.

Currently in linux-omap you won't hit this because the not found case
is never executed, unless you start modifying powerdomains and their
wakeup/sleep deps.

omap2_init_clk_clkdm() is called as part of the chip architecture-specific

Subject: OMAP2/3 PM: create the OMAP PM interface and add a default OMAP PM
 no-op layer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The interface provides device drivers, CPUFreq, and DSPBridge with a
means of controlling OMAP power management parameters that are not yet
supported by the Linux PM PMQoS interface.  Copious documentation is
in the patch in Documentation/arm/OMAP/omap_pm and the interface
header file, arch/arm/plat-omap/include/mach/omap-pm.h.

Thanks to Rajendra Nayak <rnayak@ti.com> for adding CORE (VDD2) OPP
support and moving the OPP table initialization earlier in the event
that the clock code needs them.  Thanks to Tero Kristo
<tero.kristo@nokia.com> for fixing the parameter check in
omap_pm_set_min_bus_tput().  Jouni signed off on Tero's patch.

+
+The OMAP PM interface
+=====================
+
+This document describes the temporary OMAP PM interface.  Driver
+authors use these functions to communicate minimum latency or
+throughput constraints to the kernel power management code.
+Over time, the intention is to merge features from the OMAP PM
+interface into the Linux PM QoS code.
+
+Drivers need to express PM parameters which:
+
+- support the range of power management parameters present in the TI SRF;
+
+- separate the drivers from the underlying PM parameter
+  implementation, whether it is the TI SRF or Linux PM QoS or Linux
+  latency framework or something else;
+
+- specify PM parameters in terms of fundamental units, such as
+  latency and throughput, rather than units which are specific to OMAP
+  or to particular OMAP variants;
+
+- allow drivers which are shared with other architectures (e.g.,
+  DaVinci) to add these constraints in a way which won't affect non-OMAP
+  systems,
+
+- can be implemented immediately with minimal disruption of other
+  architectures.
+
+
+This document proposes the OMAP PM interface, including the following
+five power management functions for driver code:
+
+1. Set the maximum MPU wakeup latency:
+   (*pdata->set_max_mpu_wakeup_lat)(struct device *dev, unsigned long t)
+
+2. Set the maximum device wakeup latency:
+   (*pdata->set_max_dev_wakeup_lat)(struct device *dev, unsigned long t)
+
+3. Set the maximum system DMA transfer start latency (CORE pwrdm):
+   (*pdata->set_max_sdma_lat)(struct device *dev, long t)
+
+4. Set the minimum bus throughput needed by a device:
+   (*pdata->set_min_bus_tput)(struct device *dev, u8 agent_id, unsigned long r)
+
+5. Return the number of times the device has lost context
+   (*pdata->get_dev_context_loss_count)(struct device *dev)
+
+
+Further documentation for all OMAP PM interface functions can be
+found in arch/arm/plat-omap/include/mach/omap-pm.h.
+
+
+The OMAP PM layer is intended to be temporary
+---------------------------------------------
+
+The intention is that eventually the Linux PM QoS layer should support
+the range of power management features present in OMAP3.  As this
+happens, existing drivers using the OMAP PM interface can be modified
+to use the Linux PM QoS code; and the OMAP PM interface can disappear.
+
+
+Driver usage of the OMAP PM functions
+-------------------------------------
+
+As the 'pdata' in the above examples indicates, these functions are
+exposed to drivers through function pointers in driver .platform_data
+structures.  The function pointers are initialized by the board-*.c
+files to point to the corresponding OMAP PM functions:
+.set_max_dev_wakeup_lat will point to
+omap_pm_set_max_dev_wakeup_lat(), etc.  Other architectures which do
+not support these functions should leave these function pointers set
+to NULL.  Drivers should use the following idiom:
+
+        if (pdata->set_max_dev_wakeup_lat)
+            (*pdata->set_max_dev_wakeup_lat)(dev, t);
+
+The most common usage of these functions will probably be to specify
+the maximum time from when an interrupt occurs, to when the device
+becomes accessible.  To accomplish this, driver writers should use the
+set_max_mpu_wakeup_lat() function to to constrain the MPU wakeup
+latency, and the set_max_dev_wakeup_lat() function to constrain the
+device wakeup latency (from clk_enable() to accessibility).  For
+example,
+
+        /* Limit MPU wakeup latency */
+        if (pdata->set_max_mpu_wakeup_lat)
+            (*pdata->set_max_mpu_wakeup_lat)(dev, tc);
+
+        /* Limit device powerdomain wakeup latency */
+        if (pdata->set_max_dev_wakeup_lat)
+            (*pdata->set_max_dev_wakeup_lat)(dev, td);
+
+        /* total wakeup latency in this example: (tc + td) */
+
+The PM parameters can be overwritten by calling the function again
+with the new value.  The settings can be removed by calling the
+function with a t argument of -1 (except in the case of
+set_max_bus_tput(), which should be called with an r argument of 0).
+
+The fifth function above, omap_pm_get_dev_context_loss_count(),
+is intended as an optimization to allow drivers to determine whether the
+device has lost its internal context.  If context has been lost, the
+driver must restore its internal context before proceeding.
+
+
+Other specialized interface functions
+-------------------------------------
+
+The five functions listed above are intended to be usable by any
+device driver.  DSPBridge and CPUFreq have a few special requirements.
+DSPBridge expresses target DSP performance levels in terms of OPP IDs.
+CPUFreq expresses target MPU performance levels in terms of MPU
+frequency.  The OMAP PM interface contains functions for these
+specialized cases to convert that input information (OPPs/MPU
+frequency) into the form that the underlying power management
+implementation needs:
+
+6. (*pdata->dsp_get_opp_table)(void)
+
+7. (*pdata->dsp_set_min_opp)(u8 opp_id)
+
+8. (*pdata->dsp_get_opp)(void)
+
+9. (*pdata->cpu_get_freq_table)(void)
+
+10. (*pdata->cpu_set_freq)(unsigned long f)
+
+11. (*pdata->cpu_get_freq)(void)

Subject: OMAP2/3/4 PRCM: add module IDLEST wait code

After a hardware module's clocks are enabled, Linux must wait for it
to indicate readiness via its IDLEST bit before attempting to access
the device, otherwise register accesses to the device may trigger an
abort.  This has traditionally been implemented in the clock
framework, but this is the wrong place for it: the clock framework
doesn't know which module clocks must be enabled for a module to leave
idle; and if a module is not in smart-idle mode, it may never leave
idle at all.  This type of information is best stored in a
per-hardware module data structure (coming in a following patch),
rather than a per-clock data structure.  The new code will use these new
functions to handle waiting for modules to enable.

Once hardware module data is filled in for all of the on-chip devices,
the clock framework code to handle IDLEST waiting can be removed.

From b3c6df3ab2b17cd7ddf927d39a64f235b25ac8d4 Mon Sep 17 00:00:00 2001
From: Paul Walmsley <paul@pwsan.com>

Subject: OMAP2/3 board-*.c files: read bootloader configuration earlier

Most board-*.c files read configuration data from the bootloader in
their .init_machine() function.  This needs to happen earlier, at some
point before omap2_init_common_hw() is called.  This is because a
future patch will use the bootloader serial console port information
to enable the UART clocks earlier, immediately after omap2_clk_init().
This is in turn necessary since otherwise clock tree usecounts on
clocks like dpll4_m2x2_ck will be bogus, which can cause the
currently-active console UART clock to be disabled during boot.

From 63c852384125ca0eff0e695f92cbbd439bed4aa3 Mon Sep 17 00:00:00 2001

Subject: OMAP2/3/4: create omap_hwmod layer

OMAP SoCs can be considered a collection of hardware IP blocks
connected by various interconnects.  The bus topology and device
integration data is somewhat more complex than platform_device can
encode.  This patch creates code and structures to manage information
about OMAP on-chip devices ("hardware modules") and their integration
to the rest of the chip.  Hardware module data is intended to be
generated dynamically from the TI hardware database for the OMAP4
chips and beyond, easing Linux support for new chip variants.

This code currently:

- resets and configures all hardware modules upon startup, reducing bootloader
  dependencies;

- provides hooks for Linux driver model code to enable, idle, and shutdown
  hardware modules (forthcoming patch);

- waits for hardware modules to leave idle once their clocks
  are enabled and OCP_SYSCONFIG bits are set appropriately.

- provides a means to pass arbitrary IP block configuration data (e.g.,
  FIFO size) to the device driver (via the dev_attr void pointer)

In the future this code is intended to:

- estimate interconnect bandwidth and latency characteristics to
  ensure constraints are satisfied during DVFS

- provide *GRPSEL bit data to the powerdomain code

- handle pin/ball muxing for devices

- generate IO mapping information dynamically

- supply device firewall configuration data

- provide hardware module data to other on-chip coprocessor software

- allow the removal of the "disable unused clocks" code in the OMAP2/3
  clock code

This patch represents a collaborative effort involving many people from TI,
Nokia, and the Linux-OMAP community.

From b04b65ab5b4fc86af073424af6295be4e067adf3 Mon Sep 17 00:00:00 2001
From: Paul Walmsley <paul@pwsan.com>
Date: Thu, 3 Sep 2009 20:14:05 +0300
Subject: OMAP2/3/4 core: create omap_device layer

The omap_device code provides a mapping of omap_hwmod structures into
the platform_device system, and includes some details on external
(board-level) integration.  This allows drivers to enable, idle, and
shutdown on-chip device resources, including clocks, regulators, etc.
The resources enabled and idled are dependent on the device's maximum
wakeup latency constraint (if present).

At the moment, omap_device functions are intended to be called from
platform_data function pointers.  Ideally in the future these
functions will be called from either subarchitecture-specific
platform_data activate, deactivate functions, or via an custom
bus/device type for OMAP.

+ *
+ *
+ * Guidelines for usage by driver authors:
+ *
+ * 1. These functions are intended to be used by device drivers via
+ * function pointers in struct platform_data.  As an example,
+ * omap_device_enable() should be passed to the driver as
+ *
+ * struct foo_driver_platform_data {
+ * ...
+ *      int (*device_enable)(struct platform_device *pdev);
+ * ...
+ * }
+ *
+ * Note that the generic "device_enable" name is used, rather than
+ * "omap_device_enable".  This is so other architectures can pass in their
+ * own enable/disable functions here.
+ *
+ * This should be populated during device setup:
+ *
+ * ...
+ * pdata->device_enable = omap_device_enable;
+ * ...
+ *
+ * 2. Drivers should first check to ensure the function pointer is not null
+ * before calling it, as in:
+ *
+ * if (pdata->device_enable)
+ *     pdata->device_enable(pdev);
+ *
+ * This allows other architectures that don't use similar device_enable()/
+ * device_shutdown() functions to execute normally.
+ *
+ * ...
+ *
+ * Suggested usage by device drivers:
+ *
+ * During device initialization:
+ * device_enable()
+ *
+ * During device idle:
+ * (save remaining device context if necessary)
+ * device_idle();
+ *
+ * During device resume:
+ * device_enable();
+ * (restore context if necessary)
+ *
+ * During device shutdown:
+ * device_shutdown()
+ * (device must be reinitialized at this point to use it again)

Subject: ARM: 5691/1: fix cache aliasing issues between kmap() and
 kmap_atomic() with highmem

Let's suppose a highmem page is kmap'd with kmap().  A pkmap entry is
used, the page mapped to it, and the virtual cache is dirtied.  Then
kunmap() is used which does virtually nothing except for decrementing a
usage count.

Then, let's suppose the _same_ page gets mapped using kmap_atomic().
It is therefore mapped onto a fixmap entry instead, which has a
different virtual address unaware of the dirty cache data for that page
sitting in the pkmap mapping.

Fortunately it is easy to know if a pkmap mapping still exists for that
page and use it directly with kmap_atomic(), thanks to kmap_high_get().

And actual testing with a printk in the added code path shows that this
condition is actually met *extremely* frequently.  Seems that we've been
quite lucky that things have worked so well with highmem so far.

Subject: ARM: 5640/1: This patch modifies the support of AC97 on the
 at91sam9263 ek board

This patch modifies the support of AC97 on the at91sam9263 ek board, so it would
share the code with AVR32.
Plus it removes a typo in at91sam9263_devices.c.

Subject: [ARM] pxa/sharpsl_pm: zaurus c3000 aka spitz: fix resume

sharpsl_pm.c code tries to read battery state very early during
resume, but those battery meters are connected on SPI and that's only
resumed way later.

Replace the check with simple checking of battery fatal signal, that
actually works at this stage.

This was #define'd as 0 on all platforms, so let's get rid of it.

This change makes pci_scan_slot() slightly easier to read.

Subject: ARM: Fix pfn_valid() for sparse memory

On OMAP platforms, some people want to declare to segment up the memory
between the kernel and a separate application such that there is a hole
in the middle of the memory as far as Linux is concerned.  However,
they want to be able to mmap() the hole.

This currently causes problems, because update_mmu_cache() thinks that
there are valid struct pages for the "hole".  Fix this by making
pfn_valid() slightly more expensive, by checking whether the PFN is
contained within the meminfo array.

Subject: DaVinci: DM646x - platform changes for vpif capture and display
 drivers

VPIF display changes (Chaithrika)

Add platform device and resource structures. Also define a platform specific
clock setup function that can be accessed by the driver to configure the clock
and CPLD.

VPIF caputure changes (Murali)

1) Modify vpif_subdev_info to add board_info, routing information and
   vpif interface configuration. Remove addr since it is part of
   board_info

2) Add code to setup channel mode and input decoder path for vpif
   capture driver

Also incorporated comments against version v0 of the patch series and
added a spinlock to protect writes to common registers

Tested on DM6467 on channel 0 using TVP514x. Following bootargs used
for drivers:

   vpif_capture.ch0_bufsize=829440 vpif_display.ch2_bufsize=829440

Subject: mfd: OMAP: Board-specifc twl4030 DPS scripts for RX51 board

Add support for Dynamic Power Switching (DPS) for the RX51 board.

These scripts are still a work-in-progress. I'll keep sending patches to
update the scripts as they are optimised.

Subject: mtd: onenand: make onenand/generic.c more generic

Remove the ARM dependency from the generic "onenand" platform device
driver.  This change makes the driver useful for other architectures as
well.  Needed for the SuperH kfr2r09 board.

Apart from the obvious Kconfig bits, the most important change is the move
away from ARM specific includes and platform data.  Together with this
change the only in-tree board code gets an update, and the driver name is
also changed gracefully break potential out of tree drivers.

The driver is also updated to allow NULL as platform data together with a
few changes to make use of resource_size() and dev_name().

From caa27b66bd7188fd063769eaf4b33533ef0709e6 Mon Sep 17 00:00:00 2001

Subject: kbuild: use INSTALLKERNEL to select customized installkernel script

Replace the use of CROSS_COMPILE to select a customized
installkernel script with the possibility to set INSTALLKERNEL
to select a custom installkernel script when running make:

    make INSTALLKERNEL=arm-installkernel install

With this patch we are now more consistent across
different architectures - they did not all support use
of CROSS_COMPILE.

The use of CROSS_COMPILE was a hack as this really belongs
to gcc/binutils and the installkernel script does not change
just because we change toolchain.

The use of CROSS_COMPILE caused troubles with an upcoming patch
that saves CROSS_COMPILE when a kernel is built - it would no
longer be installable.
[Thanks to Peter Z. for this hint]

This patch undos what Ian did in commit:

  0f8e2d62fa04441cd12c08ce521e84e5bd3f8a46
  ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh")

The patch has been lightly tested on x86 only - but all changes
looks obvious.

 INSTALL_PATH specifies where to place the updated kernel and system map

+INSTALLKERNEL
+--------------------------------------------------
+Install script called when using "make install".
+The default name is "installkernel".
+
+The script will be called with the following arguments:
+    $1 - kernel version
+    $2 - kernel image file
+    $3 - kernel map file
+    $4 - default install path (use root directory if blank)
+
+The implmentation of "make install" is architecture specific

From 51b563fc93c8cb5bff1d67a0a71c374e4a4ea049 Mon Sep 17 00:00:00 2001
From: Sam Ravnborg <sam@ravnborg.org>
Date: Sun, 20 Sep 2009 12:28:22 +0200
Subject: arm, cris, mips, sparc, powerpc, um, xtensa: fix build with bash 4.0

Albin Tonnerre <albin.tonnerre@free-electrons.com> reported:

    Bash 4 filters out variables which contain a dot in them.
    This happends to be the case of CPPFLAGS_vmlinux.lds.
    This is rather unfortunate, as it now causes
    build failures when using SHELL=/bin/bash to compile,
    or when bash happens to be used by make (eg when it's /bin/sh)

Remove the common definition of CPPFLAGS_vmlinux.lds by
pushing relevant stuff to either Makefile.build or the
arch specific kernel/Makefile where we build the linker script.

This is also nice cleanup as we move the information out where
it is used.

Notes for the different architectures touched:

arm - we use an already exported symbol
cris - we use a config symbol aleady available
       [Not build tested]
mips - the jiffies complexity has moved to vmlinux.lds.S where we need it.
       Added a few variables to CPPFLAGS - they are only used by
       the linker script.
       [Not build tested]
powerpc - removed assignment that is not needed
          [not build tested]
sparc - simplified it using $(BITS)
um - introduced a few new exported variables to deal with this
xtensa - added options to CPP invocation
         [not build tested]

From cdd6c482c9ff9c55475ee7392ec8f672eddb7be6 Mon Sep 17 00:00:00 2001
From: Ingo Molnar <mingo@elte.hu>
Date: Mon, 21 Sep 2009 12:02:48 +0200
Subject: perf: Do the big rename: Performance Counters -> Performance Events

Bye-bye Performance Counters, welcome Performance Events!

In the past few months the perfcounters subsystem has grown out its
initial role of counting hardware events, and has become (and is
becoming) a much broader generic event enumeration, reporting, logging,
monitoring, analysis facility.

Naming its core object 'perf_counter' and naming the subsystem
'perfcounters' has become more and more of a misnomer. With pending
code like hw-breakpoints support the 'counter' name is less and
less appropriate.

All in one, we've decided to rename the subsystem to 'performance
events' and to propagate this rename through all fields, variables
and API names. (in an ABI compatible fashion)

The word 'event' is also a bit shorter than 'counter' - which makes
it slightly more convenient to write/handle as well.

Thanks goes to Stephane Eranian who first observed this misnomer and
suggested a rename.

User-space tooling and ABI compatibility is not affected - this patch
should be function-invariant. (Also, defconfigs were not touched to
keep the size down.)

This patch has been generated via the following script:

  FILES=$(find * -type f | grep -vE 'oprofile|[^K]config')

  sed -i \
    -e 's/PERF_EVENT_/PERF_RECORD_/g' \
    -e 's/PERF_COUNTER/PERF_EVENT/g' \
    -e 's/perf_counter/perf_event/g' \
    -e 's/nb_counters/nb_events/g' \
    -e 's/swcounter/swevent/g' \
    -e 's/tpcounter_event/tp_event/g' \
    $FILES

  for N in $(find . -name perf_counter.[ch]); do
    M=$(echo $N | sed 's/perf_counter/perf_event/g')
    mv $N $M
  done

  FILES=$(find . -name perf_event.*)

  sed -i \
    -e 's/COUNTER_MASK/REG_MASK/g' \
    -e 's/COUNTER/EVENT/g' \
    -e 's/\<event\>/event_id/g' \
    -e 's/counter/event/g' \
    -e 's/Counter/Event/g' \
    $FILES

... to keep it as correct as possible. This script can also be
used by anyone who has pending perfcounters patches - it converts
a Linux kernel tree over to the new naming. We tried to time this
change to the point in time where the amount of pending patches
is the smallest: the end of the merge window.

Namespace clashes were fixed up in a preparatory patch - and some
stylistic fallout will be fixed up in a subsequent patch.

( NOTE: 'counters' are still the proper terminology when we deal
  with hardware registers - and these sed scripts are a bit
  over-eager in renaming them. I've undone some of that, but
  in case there's something left where 'counter' would be
  better than 'event' we can undo that on an individual basis
  instead of touching an otherwise nicely automated patch. )

- *
- * The value and mask are divided up into (non-overlapping) bitfields
- * of three different types:
- *
- * Select field: this expresses the constraint that some set of bits
- * in MMCR* needs to be set to a specific value for this event.  For a
- * select field, the mask contains 1s in every bit of the field, and
- * the value contains a unique value for each possible setting of the
- * MMCR* bits.  The constraint checking code will ensure that two events
- * that set the same field in their masks have the same value in their
- * value dwords.
- *
- * Add field: this expresses the constraint that there can be at most
- * N events in a particular class.  A field of k bits can be used for
- * N <= 2^(k-1) - 1.  The mask has the most significant bit of the field
- * set (and the other bits 0), and the value has only the least significant
- * bit of the field set.  In addition, the 'add_fields' and 'test_adder'
- * in the struct power_pmu for this processor come into play.  The
- * add_fields value contains 1 in the LSB of the field, and the
- * test_adder contains 2^(k-1) - 1 - N in the field.
- *
- * NAND field: this expresses the constraint that you may not have events
- * in all of a set of classes.  (For example, on PPC970, you can't select
- * events from the FPU, ISU and IDU simultaneously, although any two are
- * possible.)  For N classes, the field is N+1 bits wide, and each class
- * is assigned one bit from the least-significant N bits.  The mask has
- * only the most-significant bit set, and the value has only the bit
- * for the event's class set.  The test_adder has the least significant
- * bit set in the field.
- *
- * If an event is not subject to the constraint expressed by a particular
- * field, then it will have 0 in both the mask and value for that field.

+ * The power_pmu.get_constraint function returns a 32/64-bit value and
+ * a 32/64-bit mask that express the constraints between this event_id and
+ * other events.
+ *
+ * The value and mask are divided up into (non-overlapping) bitfields
+ * of three different types:
+ *
+ * Select field: this expresses the constraint that some set of bits
+ * in MMCR* needs to be set to a specific value for this event_id.  For a
+ * select field, the mask contains 1s in every bit of the field, and
+ * the value contains a unique value for each possible setting of the
+ * MMCR* bits.  The constraint checking code will ensure that two events
+ * that set the same field in their masks have the same value in their
+ * value dwords.
+ *
+ * Add field: this expresses the constraint that there can be at most
+ * N events in a particular class.  A field of k bits can be used for
+ * N <= 2^(k-1) - 1.  The mask has the most significant bit of the field
+ * set (and the other bits 0), and the value has only the least significant
+ * bit of the field set.  In addition, the 'add_fields' and 'test_adder'
+ * in the struct power_pmu for this processor come into play.  The
+ * add_fields value contains 1 in the LSB of the field, and the
+ * test_adder contains 2^(k-1) - 1 - N in the field.
+ *
+ * NAND field: this expresses the constraint that you may not have events
+ * in all of a set of classes.  (For example, on PPC970, you can't select
+ * events from the FPU, ISU and IDU simultaneously, although any two are
+ * possible.)  For N classes, the field is N+1 bits wide, and each class
+ * is assigned one bit from the least-significant N bits.  The mask has
+ * only the most-significant bit set, and the value has only the bit
+ * for the event_id's class set.  The test_adder has the least significant
+ * bit set in the field.
+ *
+ * If an event_id is not subject to the constraint expressed by a particular
+ * field, then it will have 0 in both the mask and value for that field.

-/* Sparc64 chips have two performance counters, 32-bits each, with
- * overflow interrupts generated on transition from 0xffffffff to 0.
- * The counters are accessed in one go using a 64-bit register.
- *
- * Both counters are controlled using a single control register.  The
- * only way to stop all sampling is to clear all of the context (user,
- * supervisor, hypervisor) sampling enable bits.  But these bits apply
- * to both counters, thus the two counters can't be enabled/disabled
- * individually.
- *
- * The control register has two event fields, one for each of the two
- * counters.  It's thus nearly impossible to have one counter going
- * while keeping the other one stopped.  Therefore it is possible to
- * get overflow interrupts for counters not currently "in use" and
- * that condition must be checked in the overflow interrupt handler.
- *
- * So we use a hack, in that we program inactive counters with the
- * "sw_count0" and "sw_count1" events.  These count how many times
- * the instruction "sethi %hi(0xfc000), %g0" is executed.  It's an
- * unusual way to encode a NOP and therefore will not trigger in
- * normal code.

+/* Sparc64 chips have two performance counters, 32-bits each, with
+ * overflow interrupts generated on transition from 0xffffffff to 0.
+ * The counters are accessed in one go using a 64-bit register.
+ *
+ * Both counters are controlled using a single control register.  The
+ * only way to stop all sampling is to clear all of the context (user,
+ * supervisor, hypervisor) sampling enable bits.  But these bits apply
+ * to both counters, thus the two counters can't be enabled/disabled
+ * individually.
+ *
+ * The control register has two event fields, one for each of the two
+ * counters.  It's thus nearly impossible to have one counter going
+ * while keeping the other one stopped.  Therefore it is possible to
+ * get overflow interrupts for counters not currently "in use" and
+ * that condition must be checked in the overflow interrupt handler.
+ *
+ * So we use a hack, in that we program inactive counters with the
+ * "sw_count0" and "sw_count1" events.  These count how many times
+ * the instruction "sethi %hi(0xfc000), %g0" is executed.  It's an
+ * unusual way to encode a NOP and therefore will not trigger in
+ * normal code.

From ceb69a899f0819bce825083bd487c6afacc0d1b4 Mon Sep 17 00:00:00 2001
From: Mikael Pettersson <mikpe@it.uu.se>

Subject: ixp4xx: timer and clocks cleanups
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch does a few simple cleanups of the ixp4xx timer
and clocksource/clockevent code in mach-ixp4xx/common.c:

- ixp4xx_clocksource_init() is static and always returns 0,
  which is ignored by its only caller: make it return void
- ixp4xx_clockevent_init(): ditto
- ixp4xx_get_cycles() is only referenced locally: make it static
- use the ixp4xx_timer_irq.dev_id field to pass &clockevent_ixp4xx
  to ixp4xx_timer_interrupt() via its dev_id parameter, allowing
  the code in ixp4xx_timer_interrupt() to be smaller and faster

Tested on an ixp420 machine (ds101).

Subject: ixp4xx: arch_idle() documentation fixup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The body of the mach-ixp4xx arch_idle() is mysteriously
disabled by an #if 0 .. #endif. Normally one would expect
to find a call to cpu_do_idle() there, but that call is
disabled, even though cpu_do_idle() is implemented for
XScale cores (and ixp4xx is one).

The explanation can be found in the ixp42x developer's manual
which states that the XScale core clock and power management
registers aren't implemented on ixp42x [3.5.2.2].

Also, the disabled code has suffered from bit rot:
- it checks hlt_counter which is obsolete, as that variable
  and all related code now is private to kernel/process.c
- it passes too many parameters to cpu_do_idle()

So this patch:
- adds a comment before the #if 0 to explain why
  cpu_do_idle() mustn't be called on ixp4xx
- removes the obsolete test of hlt_counter and the
  obsolete parameter to cpu_do_idle()

This is purely a documentation fixup and changes no
generated code. Even so, it has been tested on an
ixp420 machine (ds101).

Subject: arches: drop superfluous casts in nr_free_pages() callers

Commit 96177299416dbccb73b54e6b344260154a445375 ("Drop free_pages()")
modified nr_free_pages() to return 'unsigned long' instead of 'unsigned
int'.  This made the casts to 'unsigned long' in most callers superfluous,
so remove them.

From 90f72aa58bbf076b68e289fbd71eb829bc505923 Mon Sep 17 00:00:00 2001
From: Arnd Bergmann <arnd@arndb.de>

Subject: mm: add MAP_HUGETLB for mmaping pseudo-anonymous huge page regions

Add a flag for mmap that will be used to request a huge page region that
will look like anonymous memory to user space.  This is accomplished by
using a file on the internal vfsmount.  MAP_HUGETLB is a modifier of
MAP_ANONYMOUS and so must be specified with it.  The region will behave
the same as a MAP_ANONYMOUS region using small pages.

The patch also adds the MAP_STACK flag, which was previously defined only
on some architectures but not on others.  Since MAP_STACK is meant to be a
hint only, architectures can define it without assigning a specific
meaning to it.

From 6e17b17f1fc7b2f24383a693d63550d9e1460081 Mon Sep 17 00:00:00 2001
From: Arnd Bergmann <arnd@arndb.de>
Date: Mon, 21 Sep 2009 17:03:48 -0700
Subject: mm: remove duplicate asm/mman.h files

A number of architectures have identical asm/mman.h files so they can all
be merged by using the new generic file.

The remaining asm/mman.h files are substantially different from each
other.

Subject: ARM: OMAP: mmc-twl4030: add context loss counter support

PM dynamic OFF state results in context loss.  That is, the host
controller has been powered off at some point, which means the registers
have been reset.  The driver must detect when this happens, and restore
the context.  This patch adds the means to detect context loss.

Note, the PM side is not yet implemented.

Subject: AT91: atmel-mci: Platform configuration to the the atmel-mci driver

Created a modified version of the at91sam9g20 evaluation kit platform
(board-sam9g20ek-2slot-mmc.c) and device support to make use of the
updated atmel-mci driver.

As the use of two slots modify GPIO pin allocation, we create another
board file.

This requires getting the most updated arch/arm/tools/mach-types from
http://www.arm.linux.org.uk/developer/machines/download.php to have the machine
type for the at91sam9g20ek-2slot-mmc board.

+ *              pins, numbers < 0 mean internal CSPI chipselects according
+ *              to MXC_SPI_CS(). Normally you want to use gpio based chip
+ *              selects as the CSPI module tries to be intelligent about
+ *              when to assert the chipselect: The CSPI module deasserts the
+ *              chipselect once it runs out of input data. The other problem
+ *              is that it is not possible to mix between high active and low
+ *              active chipselects on one single bus using the internal
+ *              chipselects. Unfortunately Freescale decided to put some
+ *              chipselects on dedicated pins which are not usable as gpios,
+ *              so we have to support the internal chipselects.

Subject: spi: McSPI support for OMAP4

tAdd adds McSPI support for OMAP4430 SDP platform.  All the base addresses
are changed between OMAP1/2/3 and OMAP4.  The fields of the resource
structures are filled at runtime to have McSPI support on OMAP4.

From fb49b78452503f6cdf8b243ccb40cda81aae9998 Mon Sep 17 00:00:00 2001
From: Kevin Hilman <khilman@mvista.com>
Date: Tue, 22 Sep 2009 16:46:48 -0700
Subject: omapfb: add support for the 3430SDP LCD

The 3430SDP uses the same panel as the 2430SDP.  The main difference are
in the GPIO lines used for panel enable and backlight, and the VAUX
register/commands sent to the TWL4030 power subsystem.

Also, some misc. whitespace cleanups.

From 8fea8844a72f95ef22b108f5dc5c4237019771dd Mon Sep 17 00:00:00 2001
From: "Stanley.Miao" <stanley.miao@windriver.com>
Date: Tue, 22 Sep 2009 16:46:52 -0700
Subject: omapfb: add support for the ZOOM MDK LCD

Add glue to control the OMAP_LDP LCD as a frame buffer device using the
existing dispc.c driver under omapfb.

Patch updated for mainline kernel.  Note that the drivers/video/omap
should be updated to pass omap_lcd_config in platform_data.  The patch
should also be updated to compile if twl4030 is not selected, and
eventually to use the regulator framework.

Subject: omapfb: fix coding style / remove dead line

- use __iomem type attribute where appropriate
- expand (a ? : b) to (a ? a : b)
As suggested by Russel King <linux@arm.linux.org.uk>

- remove a dead line from omapfb_main.c

From 56f8ba83a52b9f9e3711eff8e54168ac14aa288f Mon Sep 17 00:00:00 2001

Subject: cpumask: use mm_cpumask() wrapper: arm

Makes code futureproof against the impending change to mm->cpu_vm_mask.

It's also a chance to use the new cpumask_ ops which take a pointer
(the older ones are deprecated, but there's no hurry for arch code).

Subject: headers: utsname.h redux

* remove asm/atomic.h inclusion from linux/utsname.h --
   not needed after kref conversion
 * remove linux/utsname.h inclusion from files which do not need it

NOTE: it looks like fs/binfmt_elf.c do not need utsname.h, however
due to some personality stuff it _is_ needed -- cowardly leave ELF-related
headers and files alone.
