Make sure that we patch the ACCCTL register as the first thing when the
driver loads, thus configuring I2C fast mode and i2c access for dual access
registers.

In certain boards the source for the clk32k clock can be gated. In these
boards the clk32k clock can be provided to the driver and it is going to be
enabled/disabled when it is needed.
If the clk32k clock is not provided the driver will assume that it is always
running.

All boards using twl6040 configures the i2c bus to 400KHz. While twl6040's
defaults to normal mode (100KHz). So far twl6040 has no problem with i2c
communication in this configuration it is safer to select fast i2c mode.

If for some reason the boot loader enabled the audpwron GPIO we will have
pending IRQs to be handled. This seams to break twl6040 for some reason
leading to non working i2c communication (i2c timeouts). Clearing the INTID
register after we requested the audpwron GPIO (and set it to low) will
ensure that the chip will operate normally in this case as well.

The supply aliases for the MFD devices were being added using devres but
the device hasn't been added at this point and as such we can't use
devres.
The MFD already has a function that removes devices this patch uses the
non-devres versions of the supply alias functions and adds an unregister
in mfd_remove_devices_fn.

The valid gpio is GPIO0 ~ GPIO58, so ngpio should be 59.
This patch also renames RDC321X_MAX_GPIO to RDC321X_NUM_GPIO because it
actually means the number of available GPIOs.

The rtc-s5m driver does not support all of S2M and S5M chipsets
supported by main MFD sec-core driver. For such chipsets unsupported by
rtc-s5m, the MFD sec-core driver initialized regmap with default config.
This config in such cases wouldn't work at all.
The main MFD sec-core driver shouldn't initialize regmap for child
drivers which is not used by them and even not valid.
Move the allocation of RTC I2C dummy device and initialization of RTC
regmap from main MFD sec-core driver to the rtc-s5m driver. The rtc-s5m
driver will use proper regmap config for supported devices.

After request_threaded_irq() is called there is a chance that an interrupt
may occur before the 'mc13xxx->lock' is initialized, which will trigger a kernel
oops.
In order to prevent that, move the initialization of 'mc13xxx->lock' prior to
requesting the interrupts.

different feature sets.

The TPS658640 has a different set of output voltage for most LDO and

Pull ACPI and power management fixes from Rafael Wysocki:
"Still fixing regressions (partly by reverting commits that broke
things for people), fixing other stable-candidate bugs and adding some
blacklist entries for ACPI video and _OSI.
Two ACPICA regression fixes (one recent and one for a 3.14 commit), a
fix for an ACPI-related regression in TPM (introduced in 3.14), a
revert of the ACPI AC driver conversion in 3.13 that went wrong for an
unknown reason, two reverts of commits that attempted to remove an old
user space interface in /proc and broke some utilities, in 3.13 too, a
fix for a CPU hotplug bug in the ACPI processor driver (stable
material), two (stable candidate) fixes for intel_pstate and a few new
blacklist entries, mostly for systems that shipped with Windows 8.
Specifics:
- ACPICA fix for a stale pointer access introduced by a recent commit
in the XSDT validation code from Lv Zheng.
- ACPICA fix for the default value of the command line switch to
favor 32-bit FADT addresses (in case there's a conflict between a
64-bit and a 32-bit address). The previous default was that the
32-bit version would take precedence and we tried to change it to
the other way around and it didn't work. From Lv Zheng.
- A TPM commit related to ACPI _DSM in 3.14 caused the driver to
refuse to load if a specific _DSM was missing and that broke resume
from system suspend on Chromebooks that require the TPM hardware to
be restored to a working state during resume by the OS. Restore
the old behavior to load the driver if the _DSM in question is not
present, but prevent it from using the feature the _DSM is for.
- ACPI AC driver conversion in 3.13 broke thermal management on at
least one machine and has to be reverted. From Guenter Roeck.
- Two reverts of 3.13 commits that attempted to remove the old ACPI
battery interface in /proc, but turned out to break some utilities
still using that interface. From Lan Tianyu.
- ACPI processor driver fix to prevent acpi_processor_add() from
modifying the CPU device's .offline field which leads to breakage
if the initial online of the CPU fails. From Igor Mammedov.
- Two intel_pstate fixes, one to take a BayTrail documentation update
into account and one to avoid forcing the maximum P-state on init
which causes CPU PM trouble on systems with P-states coordination
when one of the CPU cores is initialized after an offline/online
cycle triggered by user space. Both stable candidates, from Dirk
Brandewie.
- Fix for the ACPI video DMI blacklist entry for Dell Inspiron 7520
from Aaron Lu.
- Two new ACPI video blacklist entries for machines shipping with
Win8 that need to use native backlight so that it can be controlled
in a usual way (which doesn't work otherwise due bugs in the ACPI

The commit e783c51 (ahci: imx: software workaround for phy reset issue
in resume) calls imx_sata_phy_reset() to reset phy immediately after
SATA MPLL is enabled. It seems working fine mostly, but fails in some
case as below.
...
ahci-imx 2200000.sata: failed to reset phy: -110
ahci-imx: probe of 2200000.sata failed with error -110
After talking to the designer, we learnt that when enabling i.MX6Q SATA
MPLL, we need to wait 100us for it to settle down for safety. Add this
required delay to fix above failure.

On each processed XCOPY command, two "kmalloc-512" memory objects are
leaked. These represent two allocations of struct xcopy_pt_cmd in
target_core_xcopy.c.
The reason for the memory leak is that the cmd_kref field is not
initialized (thus, it is zero because the allocations were done with
kzalloc). When we decrement zero kref in target_put_sess_cmd, the result
is not zero, thus target_release_cmd_kref is not called.
This patch fixes the bug by moving kref initialization from
target_get_sess_cmd to transport_init_se_cmd (this function is called from
target_core_xcopy.c, so it will correctly initialize cmd_kref). It can be
easily verified that all code that calls target_get_sess_cmd also calls
transport_init_se_cmd earlier, thus moving kref_init shouldn't introduce
any new problems.

Commit ee1de406ba6eb1 ("random: simplify accounting logic") simplified
things too much, in that it allows the following to trigger an
overflow that results in a BUG_ON crash:
dd if=/dev/urandom of=/dev/zero bs=67108707 count=1
Thanks to Peter Zihlstra for discovering the crash, and Hannes
Frederic for analyizing the root cause.

The value written to PLLE_AUX was incorrect due to a wrong variable
being used. Without this fix SATA does not work.

Seems it helps some users, but causes issues for other users:
https://bugzilla.redhat.com/show_bug.cgi?id=1089545
So lets drop it for now until we've figured out a better fix.

Use a correct pipe type when filling un interrupt urbs. This should
finally take care of the WARN() messages on the console when USB urbs
are submitted.

Just like for pSCSI, if the transport sets get_write_cache, then it is
not valid to enable write cache emulation for it. Return an error.

This patch explicitly disables Immediate + Unsolicited Data for ISER
connections during login in iscsi_login_zero_tsih_s2() when protection
has been enabled for the session by the underlying hardware.
This is currently required because protection / signature memory regions
(MRs) expect T10 PI to occur on RDMA READs + RDMA WRITEs transfers, and
not on a immediate data payload associated with ISCSI_OP_SCSI_CMD, or
unsolicited data-out associated with a ISCSI_OP_SCSI_DATA_OUT.
v2 changes:
- Add TARGET_PROT_DOUT_INSERT check (Sagi)
- Add pr_debug noisemaker (Sagi)
- Add goto to avoid early return from MRDSL check (nab)
