      Pull GPIO updates from Linus Walleij:
 "Here is the bulk of GPIO changes for the v4.4 development cycle.

  The only changes hitting outside drivers/gpio are in the pin control
  subsystem and these seem to have settled nicely in linux-next.

  Development mistakes and catfights are nicely documented in the
  reverts as you can see.  The outcome of the ABI fight is that we're
  working on a chardev ABI for GPIO now, where hope to show results for
  the v4.5 kernel.

  Summary of changes:

  GPIO core:
   - Define and handle flags for open drain/open collector and open
     source/open emitter, also know as "single-ended" configurations.
   - Generic request/free operations that handle calling out to the
     (optional) pin control backend.
   - Some refactoring related to an ABI change that did not happen, yet
     provide useful.
   - Added a real-time compliance checklist.  Many GPIO chips have
     irqchips, and need to think this over with the RT patches going
     upstream.
   - Restructure, fix and clean up Kconfig menus a bit.

  New drivers:
   - New driver for AMD Promony.
   - New driver for ACCES 104-IDIO-16, a port-mapped I/O card,
     ISA-style.  Very retro.

  Subdriver changes:
   - OMAP changes to handle real time requirements.
   - Handle trigger types for edge and level IRQs on PL061 properly.  As
     this hardware is very common it needs to set a proper example for
     others to follow.
   - Some container_of() cleanups.
   - Delete the unused MSM driver in favor of the driver that is
     embedded inside the pin control driver.
   - Cleanup of the ath79 GPIO driver used by many, many OpenWRT router
     targets.
   - A consolidated IT87xx driver replacing the earlier very specific
     IT8761e driver.
   - Handle the TI TCA9539 in the PCA953x driver.  Also handle ACPI
     devices in this subdriver.
   - Drop xilinx arch dependencies as these FPGAs seem to profilate over
     a few different architectures.  MIPS and ARM come to mind"

      Linus Torvalds authored 
      Pull pin control updates from Linus Walleij:
 "This is the big bulk of pin control changes for the v4.4 kernel
  development cycle.  Development pace is high in pin control again this
  merge window.  28 contributors, 83 patches.

  It hits a few sites outside the pin control subsystem:

   - Device tree bindings in Documentation (as usual)
   - MAINTAINERS
   - drivers/base/* for the "init" state handling by Doug Anderson.
     This has been ACKed by Greg.
   - drivers/usb/renesas_usbhs/rcar2.c, for a dependent Renesas change
     in the USB subsystem.  This has been ACKed by both Greg and Felipe.
   - arch/arm/boot/dts/sama5d2.dtsi - this should ideally have gone
     through the ARM SoC tree but ended up here.

  This time I am using Geert Uytterhoeven as submaintainer for SH PFC
  since the are three-four people working in parallel with new Renesas
  ASICs.

  Summary of changes:

  Infrastructure:

   - Doug Anderson wrote a patch adding an "init" state different from
     the "default" state for pin control state handling in the core
     framework.  This is applied before the driver's probe() call if
     defined and takes precedence over "default".  If both are defined,
     "init" will be applied *before* probe() and "default" will be
     applied *after* probe().

  Significant subdriver improvements:

   - SH PFC is switched to getting GPIO ranges from the device tree
     ranges property on DT platforms.
   - Got rid of CONFIG_ARCH_SHMOBILE_LEGACY, we are all modernized.
   - Got rid of SH PFC hardcoded IRQ numbers.
   - Allwinner sunxi external interrupt through the "r" controller.
   - Moved the Cygnus driver to use DT-provided GPIO ranges.

  New drivers:

   - Atmel PIO4 pin controller for the SAMA4D2 family

  New subdrivers:

   - Rockchip RK3036 subdriver
   - Renesas SH PFC R8A7795 subdriver
   - Allwinner sunxi A83T PIO subdriver
   - Freescale i.MX7d iomux lpsr subdriver
   - Marvell Berlin BG4CT subdriver
   - SiRF Atlas 7 step B SoC subdriver
   - Intel Broxton SoC subdriver

  Apart from this, the usual slew if syntactic and semantic fixes"
