2015-10-26MIPS: JZ4740: Remove unused linux/leds_pwm.h includeThierry Reding
The board code never sets up a leds-pwm device, so including the header is not necessary.

2015-10-26MIPS: JZ4740: Use PWM lookup tableThierry Reding
Associate the PWM with the pwm-beeper device using a PWM lookup table. This will eventually allow the legacy function calls to pwm_request() to be removed from all consumer drivers.

2015-10-01MIPS: Fix the build on jz4740 after removing the custom gpio.hAlban Bedel
Somehow the wrong version of the patch to remove the use of custom gpio.h on mips has been merged. This patch add the missing fixes for a build error on jz4740 because linux/gpio.h doesn't provide any machine specfics definitions anymore.

2015-09-16genirq: Remove irq argument from irq flow handlersThomas Gleixner
Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument. Search and replace was done with coccinelle and some extra helper scripts around it. Thanks to Julia for her help!

2015-09-03MIPS: Remove all the uses of custom gpio.hAlban Bedel
Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS machines, and each machine type provides its own gpio.h. However only a handful really implement the GPIO API, most just forward everythings to gpiolib. The Alchemy machine is notable as it provides a system to allow implementing the GPIO API at the board level. But it is not used by any board currently supported, so it can also be removed. For most machine types we can just remove the custom gpio.h, as well as the custom wrappers if some exists. Some of the code found in the wrappers must be moved to the respective GPIO driver. A few more fixes are need in some drivers as they rely on linux/gpio.h to provides some machine specific definitions, or used asm/gpio.h instead of linux/gpio.h for the gpio API.

2015-06-21MIPS: JZ4740: introduce CONFIG_MACH_INGENICPaul Burton
In preparation for supporting Ingenic SoCs other than the JZ4740, introduce MACH_INGENIC to Kconfig & move MACH_JZ4740 to a separate entry selected by the board when appropriate. This allows MACH_INGENIC to be used to enable things generic across Ingenic SoCs.

2015-03-31MIPS: Allow platforms to specify the decompressor load addressAndrew Bresticker
Platforms which use raw zboot images may need to link the image at a fixed address if there is no other way to communicate the load address to the bootloader. Allow the per-platform Kbuild files to specify an optional zboot image load address (zload-y) and fall back to calc_vmlinuz_load_addr if unset.

Fixes sparse warnings: arch/mips/jz4740/irq.c:63:6: warning: symbol 'jz4740_irq_suspend' was not declared. Should it be static? arch/mips/jz4740/irq.c:69:6: warning: symbol 'jz4740_irq_resume' was not declared. Should it be static? Also, I've seen some elusive build errors on my automated build test where JZ4740_IRQ_BASE and NR_IRQS are missing, but I can't reproduce them manually for some reason. Anyway, mach-jz4740/irq.h should help us avoid relying on some implicit include.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO update from Linus Walleij: "This is the bulk of GPIO changes for the v3.17 development cycle, and this time we got a lot of action going on and it will continue: - The core GPIO library implementation has been split up in three different files: - gpiolib.c for the latest and greatest and shiny GPIO library code using GPIO descriptors only - gpiolib-legacy.c for the old integer number space API that we are phasing out gradually - gpiolib-sysfs.c for the sysfs interface that we are not entirely happy with, but has to live on for ABI compatibility - Add a flags argument to *gpiod_get* functions, with some backward-compatibility macros to ease transitions. We should have had the flags there from the beginning it seems, now we need to clean up the mess. There is a plan on how to move forward here devised by Alexandre Courbot and Mark Brown - Split off a special <linux/gpio/machine.h> header for the board gpio table registration, as per example from the regulator subsystem - Start to kill off the return value from gpiochip_remove() by removing the __must_check attribute and removing all checks inside the drivers/gpio directory. The rationale is: well what were we supposed to do if there is an error code? Not much: print an error message. And gpiolib already does that. So make this function return void eventually - Some cleanups of hairy gpiolib code, make some functions not to be used outside the library private and make sure they are not exported, remove gpiod_lock/unlock_as_irq() as the existing function is for driver-internal use and fine as it is, delete gpio_ensure_requested() as it is not meaningful anymore - Support the GPIOF_ACTIVE_LOW flag from gpio_request_one() function calls, which is logical since this is already supported when referencing GPIOs from e.g. device trees - Switch STMPE, intel-mid, lynxpoint and ACPI (!) to use the gpiolib irqchip helpers cutting down on GPIO irqchip boilerplate a bit more - New driver for the Zynq GPIO block - The usual incremental improvements around a bunch of drivers - Janitorial syntactic and semantic cleanups by Jingoo Han, and Rickard Strandqvist especially" * tag 'gpio-v3.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (37 commits) MAINTAINERS: update GPIO include files gpio: add missing includes in machine.h gpio: add flags argument to gpiod_get*() functions MAINTAINERS: Update Samsung pin control entry gpio / ACPI: Move event handling registration to gpiolib irqchip helpers gpio: lynxpoint: Convert to use gpiolib irqchip gpio: split gpiod board registration into machine header gpio: remove gpio_ensure_requested() gpio: remove useless check in gpiolib_sysfs_init() gpiolib: Export gpiochip_request_own_desc and gpiochip_free_own_desc gpio: move gpio_ensure_requested() into legacy C file gpio: remove gpiod_lock/unlock_as_irq() gpio: make gpiochip_get_desc() gpiolib-private gpio: simplify gpiochip_export() gpio: remove export of private of_get_named_gpio_flags() gpio: Add support for GPIOF_ACTIVE_LOW to gpio_request_one functions gpio: zynq: Clear pending interrupt when enabling a IRQ gpio: drop retval check enforcing from gpiochip_remove() gpio: remove all usage of gpio_remove retval in driver/gpio devicetree: Add Zynq GPIO devicetree bindings documentation ...
