Merge tag 'gpio-v4.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

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"
