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 ...

Pull ARM SoC driver changes from Olof Johansson: "A handful of driver-related changes. We've had a bunch of them going in through other branches as well, so it's only a part of what we really have this release.

This allows to use both a touchscreen and the remaining ADC channel at the same time. Also, lower the clock for the ADC as it allows to have more stable reads and this is the speed used by atmel_tsadcc. It lowers the maximum throughput rate from 440000 samples per second to 12958 samples per second. It shouldn't be an issue as the CPU is not able to keep up reading samples at that frequency.

2014-05-07ARM: at91: localize GPIO headerLinus Walleij41-12/+56
This moves the <mach/gpio.h> header in the AT91 platform down into the machine directory and removes the reliance on MACH_NEED_GPIO_H from the AT91. This does not move the platform to GENERIC_GPIO but localize the remaining work to be done for this to the mach-at91 folder.

Jonathan writes: First found of IIO fixes for the 3.15 cycle. * Fix the platform data support for the at91 adc driver. * A couple of related follow up patches get the support working again for at91sam9260 and at91sam9g45 as the earlier patch results in a device name change. * A default timer value in the at91 adc driver was bonkers. Make it sane. * Fix incorrect reporting of the integration time for the cm32181 light sensor * Fix a missing break in the ad2s1200 driver which would have give a false error return. * Make sure buffer scan mask queries from userspace return 0/1 rather than a fairly random value depending on their implementation of test_bit * Fix leak of the i2c client and a null pointer dereference in the cm36651 driver. * Fix a build warning on avr32 for the mxs-lradc (not exactly a critical combination - but the issue was real).

Pull ARM SoC cleanups from Arnd Bergmann: "These cleanup patches are mainly move stuff around and should all be harmless. They are mainly split out so that other branches can be based on top to avoid conflicts. Notable changes are: - We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no longer used (Uwe Kleine-König) - The Qualcomm MSM platform is split out into legacy mach-msm and new-style mach-qcom, to allow easier maintainance of the new hardware support without regressions (Kumar Gala) - A rework of some of the Kconfig logic to simplify multiplatform support (Rob Herring) - Samsung Exynos gets closer to supporting multiplatform (Sachin Kamat and others) - mach-bcm3528 gets merged into mach-bcm (Stephen Warren) - at91 gains some common clock framework support (Alexandre Belloni, Jean-Jacques Hiblot and other French people)" * tag 'cleanup-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (89 commits) ARM: hisi: select HAVE_ARM_SCU only for SMP ARM: efm32: allow uncompress debug output ARM: prima2: build reset code standalone ARM: at91: add PWM clock ARM: at91: move sam9261 SoC to common clk ARM: at91: prepare common clk transition for sam9261 SoC ARM: at91: updated the at91_dt_defconfig with support for the ADS7846 ARM: at91: dt: sam9261: Device Tree support for the at91sam9261ek ARM: at91: dt: defconfig: Added the sam9261 to the list of DT-enabled SOCs ARM: at91: dt: Add at91sam9261 dt SoC support ARM: at91: switch sam9rl to common clock framework ARM: at91/dt: define main clk frequency of at91sam9rlek ARM: at91/dt: define at91sam9rl clocks ARM: at91: prepare common clk transition for sam9rl SoCs ARM: at91: prepare sam9 dt boards transition to common clk ARM: at91: dt: sam9rl: Device Tree for the at91sam9rlek ARM: at91/defconfig: Add the sam9rl to the list of DT-enabled SOCs ARM: at91: Add at91sam9rl DT SoC support ARM: at91: prepare at91sam9rl DT transition ARM: at91/defconfig: refresh at91sam9260_9g20_defconfig ...

It makes no sense for sama5 support to be enabled if we don't also enable USE_OF. Making this automatic in Kconfig avoids a possible randconfig conflict between the old and new clock support code.

2014-03-21ARM: at91: fix broken "if () else" statementArnd Bergmann1-5/+1
If CONFIG_PATA_AT91 is disabled, the code in at91_add_device_cf is turned into invalid C statements due to the lack of an expression before the 'else' clause. This moves the first half of the condition inside of the #ifdef, which seems to be what the author intended.

The pata_at91 driver uses interfaces defined in the sam9_smc platform code. Since the pata driver can be a loadable module, we have to export those symbols in order to link cleanly.

2014-03-21ARM: at91: don't provide dt init code for at91x40Arnd Bergmann1-1/+1
at91x40 has no support for device tree, but Kconfig allows us to enable CONFIG_OF anyway, causing a link error in the at91 reset controller initialization. The easiest fix is to adapt the existing #ifdef to omit the broken code on at91x40 where it is never called anyway.

2014-03-21ARM: at91: split out at91x40 into a top-level optionArnd Bergmann2-11/+19
at91x40 is different from all the other at91 machines, and it is impossible to build a kernel that works on both this SoC and any of the others, even though it is possible to build a noMMU kernel for any at91 machine. By turning at91x40 into a separate top-level option, we explicitly forbid enabling invalid configurations that include mutually exclusive machines.
