      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"
