      Pull GPIO changes from Linus Walleij:
       "Here is the bulk of GPIO changes for the v3.13 development cycle.
      
        I've got ACKs for the things that affect other subsystems (or it's my
        own subsystem, like pinctrl).  Most of that pertain to an attempt from
        my side to consolidate and get rid of custom GPIO implementations in
        the ARM tree.  I will continue doing this.
      
        The main change this time is the new GPIO descriptor API, background
        for this can be found in Corbet's summary from this january in LWN:
      
          http://lwn.net/Articles/533632/
      
        Summary:
      
         - Merged the GPIO descriptor API from Alexandre Courbot.  This is a
           first step toward trying to get rid of the global GPIO numberspace
           for the future.
      
         - Add an API so that driver can flag that a certain GPIO line is
           being used by a irqchip backend for generating IRQs, so that we can
           enforce checks, like not allowing users to switch that line to an
           output at runtime, since this makes no sense.  Implemented
           corresponding calls in a few select drivers.
      
         - ACPI GPIO cleanups, refactorings and switch to using the
           descriptor-based interface.
      
         - Support for the TPS80036 Palmas GPIO variant.
      
         - A new driver for the Broadcom Kona GPIO SoC IP block.
      
         - Device tree support for the PCF857x driver.
      
         - A set of ARM GPIO refactorings with the goal of getting rid of a
           bunch of custom GPIO implementations from the arch/arm/* tree:
      
           * Move the IOP GPIO driver to the GPIO subsystem and fix all users
             to use the gpiolib API for accessing GPIOs.  Delete the old
             custom GPIO implementation.
      
           * Delete the unused custom PXA GPIO implemention.
      
           * Convert all users of the IXP4 custom GPIO implementation to use
             gpiolib and delete the custom implementation.
      
           * Delete the custom Gemini GPIO implementation, also completely
             unused.
      
         - Various cleanups and renamings"

      Pull pin control updates from Linus Walleij:
       "Main pin control pull request for the v3.13 cycle.
      
        The changes hitting arch/blackfin are ACKed by the Blackfin
        maintainer, and the device tree bindings are ACKed to the extent
        possible by someone from the device tree maintainers group.
      
         - Blackfin ADI pin control driver, we move yet another architecture
           under this subsystem umbrella.
      
         - Incremental updates to the Renesas Super-H PFC pin control driver.
           New subdriver for the r8a7791 SoC.
      
         - Non-linear GPIO ranges from the gpiolib side of things, this
           enabled simplified device tree bindings by referring entire groups
           of pins on some pin controller to act as back-end for a certain
           GPIO-chip driver.
      
         - Add the Abilis TB10x pin control driver used on the ARC
           architecture.  Also the corresponding GPIO driver is merged through
           this tree, so the ARC has full support for pins and GPIOs after
           this.
      
         - Subdrivers for Freescale i.MX1, i.MX27 and i.MX50 pin controller
           instances.  The i.MX1 and i.MX27 is an entirely new family
           (silicon) of controllers whereas i.MX50 is a variant of the
           previous supported controller.
      
         - Then the usual slew of fixes, cleanups and incremental updates"
      
      The ARC DT changes are apparently still pending, that hopefully gets
      sorted out in a timely manner.

       "There are no too intrusive changes in this update batch.  The biggest
        LOC is found in the new DICE driver, and other small changes are
        scattered over the whole sound subtree (which is a common pattern).
      
        Below are highlights:
      
         - ALSA core:
           * Memory allocation support with genpool
           * Fix blocking in drain ioctl of compress_offload

         - USB-audio:

           * Clean up endpoint handling codes
      
         - ASoC:
           * Further work on the dmaengine helpers, including support for
             configuring the parameters for DMA by reading the capabilities of
             the DMA controller which removes some guesswork and magic numbers
             from drivers.
           * A refresh of the documentation.
           * Conversions of many drivers to direct regmap API usage in order
             to allow the ASoC level register I/O code to be removed, this
             will hopefully be completed by v3.14.
           * Support for using async register I/O in DAPM, reducing the time
             taken to implement power transitions on systems that support it.
      
         - Firewire: DICE driver

       "Lots of driver updates here plus some nice new core features, the main

         - Enable support for providing a dummy regulator when we know that
           one must exist for the device to be functional.  This makes it much
           easier to add regulator support to drivers since we don't require
           that the machine integration for all systems using the device be
           updated to provide regulators.
         - Substantial reduction in the amount of busy waiting done while
           waiting for enables to complete.
         - Allow MFDs to distribute regulator supplies to child devices so we
           don't have to expose the internal structure of MFDs outside of the
           driver.

        Other notable changes are some infrastructure bits to better handle
        PCI pass-through under KVM, some bits and pieces added to the new
