 "Here is a batch of GPIO changes for v3.11.  I have agreed with Grant
  to take care of the pull requests for this development cycle.

  No special things are happening in the GPIO tree this time (nice with
  some calm) and I have been extra careful to do regression builds and
  it's well boiled in -next.

3883cbb6c1 ARM SoC specific changes
These changes are all to SoC-specific code, a total of 33 branches on
 17 platforms were pulled into this. Like last time, Renesas sh-mobile
 is now the platform with the most changes, followed by OMAP and EXYNOS.
 
 Two new platforms, TI Keystone and Rockchips RK3xxx are added in
 this branch, both containing almost no platform specific code at all,
 since they are using generic subsystem interfaces for clocks, pinctrl,
 interrupts etc. The device drivers are getting merged through the
 respective subsystem maintainer trees.
 
 One more SoC (u300) is now multiplatform capable and several others
 (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving
 towards that goal with this series but need more work.
 
 Also noteworthy is the work on PCI here, which is traditionally part of
 the SoC specific code. With the changes done by Thomas Petazzoni, we can
 now more easily have PCI host controller drivers as loadable modules and
 keep them separate from the platform code in drivers/pci/host. This has
 already led to the discovery that three platforms (exynos, spear and imx)
 are actually using an identical PCIe host controller and will be able
 to share a driver once support for spear and imx is added.
 
 Conflicts:
 * asm/glue-proc.h has one CPU type getting added that conflicts
   with another addition in 3.10-rc7
 * Simple context changes in arch/arm/Makefile and arch/arm/Kconfig

When CONFIG_I2C=m, meaning we can't build the drivers in with I2C support.
Thus don't allow the drivers to be compiled as built-in when CONFIG_I2C=m.

The real fix though is to break the driver apart into a SPI part, an I2C part
and a common part. But that's something for 3.11 while this is something for
3.10/stable.

5647ac0ad4 Removal of GENERIC_GPIO for v3.10
GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid
 cases for enableing GENERIC_GPIO without GPIOLIB, even though it is
 possible to do so which has been causing confusion and breakage. This
 branch does the work to completely eliminate GENERIC_GPIO.
 
 However, it is not trivial to just create a branch to remove it. Over
 the course of the v3.9 cycle more code referencing GENERIC_GPIO has been
 added to linux-next that conflicts with this branch. The following must
 be done to resolve the conflicts when merging this branch into mainline:
 
 * "git grep CONFIG_GENERIC_GPIO" should return 0 hits. Matches should be
   replaced with CONFIG_GPIOLIB
 * "git grep '\bGENERIC_GPIO\b'" should return 1 hit in the Chinese
   documentation.
 * Selectors of GENERIC_GPIO should be turned into selectors of GPIOLIB
 * definitions of the option in architecture Kconfig code should be deleted.
 
 Stephen has 3 merge fixup patches[1] that do the above. They are currently
 applicable on mainline as of May 2nd.

 r8a73a4, r8a73a4 and r8a7778. The bulk of the code added for these is
 for pinctrl (using the new subsystem) and for clocks (not yet using the
 common clock subsystem). The latter will have to get converted in one
 of the upcoming releases, but shmobile is not ready for that yet.
 
 The series also contains Renesas shmobile board changes, adding one
 board file for each of the three new SoCs.  These boards are using a
 mix of classic and device-tree based probing, as there is still a lot of
 infrastructure in shmobile that has not been converted to DT yet. Once
 those are resolved to the degree that no board specific setup code is
 needed, they can get folded into the respective SoC setup files.

119f5e448d gpio: Renesas R-Car GPIO driver V3
This patch is V3 of a GPIO driver for the R-Car series of
SoCs from Renesas. This driver is designed to be reusable
between multiple SoCs that share the same basic building block,
but so far it has only been used on R-Car H1 (r8a7779).

Each driver instance handles 32 GPIOs with individually
maskable IRQs. The driver operates on a single I/O memory
range and the 32 GPIOs are hooked up a single interrupt.

In the case of R-Car H1 either external IRQ pins or GPIOs
with interrupts can be used for on-board interupts. For
external IRQs 4 pins are supported, and in the case of GPIO
there are 202 GPIOS as 202 interrupts hooked up via 6 driver
instances and to the GIC and the Cortex-A9 Quad.

At this point this driver is interfacing as a regular
platform device driver. In the future DT support will be
submitted as an incremental feature patch.

MFD_CORE which itself depends on GENERIC_HARDIRQ support.
So add this dependency to these two drivers as well to prevent
selection of MFD_CORE.

6a89a314ab gpio: devm_gpio_* support should not depend on GPIOLIB
Some architectures (e.g. blackfin) provide gpio API without requiring
GPIOLIB support (ARCH_WANT_OPTIONAL_GPIOLIB).  devm_gpio_* functions
should also work for these architectures, since they do not really
depend on GPIOLIB.

Add a new option GPIO_DEVRES (enabled by default) to control the build
of devres.c.  It also removes the empty version of devm_gpio_*
functions for !GENERIC_GPIO build from linux/gpio.h, and moves the
function declarations from asm-generic/gpio.h into linux/gpio.h.

2dfea3803d This is the MFD patch set for the 3.8 merge window.
We have several new drivers, most of the time coming with their sub devices
 drivers:
 
 - Austria Microsystem's AS3711
 - Nano River's viperboard
 - TI's TPS80031, AM335x TS/ADC,
 - Realtek's MMC/memstick card reader
 - Nokia's retu
 
 We also got some notable cleanups and improvements:
 
 - tps6586x got converted to IRQ domains.
 - tps65910 and tps65090 moved to the regmap IRQ API.
 - STMPE is now Device Tree aware.
 - A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ
   APIs and a conversion to the recently added PWM framework.
 - sta2x11 gained regmap support.
 
 Then the rest is mostly tiny cleanups and fixes, among which we have Mark's
 wm5xxx and wm8xxx patchset.

 dove, mvebu) that came in after we had done the big multiplatform merges,
 so they were kept separate from the rest, and not separated into the
 traditional topics of cleanup/driver/platform features.
 
 For OMAP, the updates are:
 - Runtime PM conversions for the GPMC and RNG IP blocks
 - Preparation patches for the OMAP common clock framework conversion
 - clkdev alias additions required by other drivers
 - Performance Monitoring Unit (PMU) support for OMAP2, 3, and non-4430 OMAP4
 - OMAP hwmod code and data improvements
 - Preparation patches for the IOMMU runtime PM conversion
 - Preparation patches for OMAP4 full-chip retention support
 
 For Kirkwood/Dove/mvebu:
 
 - New driver for "address decoder controller" for mvebu, which
   is a piece of hardware that configures addressable devices and
   peripherals. First user is the boot rom aperture on armada XP since
   it is needed for SMP support.
 - New device tree bindings for peripherals such as gpio-fan, iconnect
   nand, mv_cesa and the above address decoder controller.
 - Some defconfig updates, mostly to enable new DT boards and a few drivers.
 - New drivers using the pincontrol subsystem for dove, kirkwood and mvebu
 - New clean gpio driver for mvebu

578f1ef91a MFD bits for the 3.7 merge window.
As usual we have a few new drivers:
 
 - TI LP8788
 - TI OMAP USB TLL
 - Maxim MAX8907
 - SMSC ECE1099
 - Dialog Semiconductor DA9055
 - A simpler syscon driver that allow us to get rid of the anatop one.
 
 Drivers are also gradually getting Device Tree and IRQ domain support.
 
 The following drivers got DT support:
 - palmas, 88pm860x, tc3589x and twl4030-audio
 
 And those ones now use the IRQ domain APIs:
 - 88pm860x, tc3589x, db8500_prcmu
 
 Also some other interesting changes:
 - Intel's ICH LPC now supports Lynx Point
 - TI's twl4030-audio added a GPO child
 - tps6527 enabled its backlight subdevice
 - The twl6030 pwm driver moved to the new PWM subsystem
 
 And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x, palmas,
 ab8500, wm8994, wm5110, max8907 and the tps65xxx family.

Fix up various annoying conflicts: the DT and IRQ domain support came in
twice and was already in 3.6. And then it was apparently rebased.

Guys, DON'T REBASE!

   the seq_file iterator interface in gpiolib.
 - A new driver for Avionic Design's N-bit GPIO expander.
 - Two instances of mutexes replaced by spinlocks from Axel Lin to
   code that is supposed to be fastpath compliant.
 - IRQ demuxer and gpio_to_irq() support for pcf857x by Kuninori
   Morimoto.
 - Dynamic GPIO numbers, device tree support, daisy chaining and some
   other fixes for the 74x164 driver by Maxime Ripard.
 - IRQ domain and device tree support for the tc3589x driver by
   Lee Jones.
 - Some conversion to use managed resources devm_* code.
 - Some instances of clk_prepare() or clk_prepare_enable() added to
   support the new, stricter common clock framework.
 - Some for_each_set_bit() simplifications.
 - Then a lot of fixes as we fixed up all of the above tripping over
   our own shoelaces and that kind of thing.

901acf5b29 gpio: pcf857x: select IRQ_DOMAIN
Patch 6e20a0a4 "gpio: pcf857x: enable gpio_to_irq() support"
added IRQ domain support to the pcf857x driver, but some configurations
(e.g. davinci_all_defconfig) don't already enable CONFIG_IRQ_DOMAIN.

Always selecting it from the Kconfig in this case is what other
such drivers do as well, and avoids these build errors:

Without this patch, building davinci_all_defconfig results in:
