GPIO bulk changes for the v3.13 development cycle

- 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.

sound updates for 3.13-rc1

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

- HD-audio:
  * Improved AMD HDMI supports
  * Intel HDMI detection improvements
  * thinkpad_acpi mute-key integration
  * New PCI ID, New ALC255,285,293 codecs, CX20952

- USB-audio:
  * New buffer size management
  * 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.

- Fireiwre: DICE driver

- Lots of small fixes for bugs reported by Coverity

regulator: Updates for v3.13

Lots of driver updates here plus some nice new core features, the main
one being the first:

 - 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.
 - Managed registeration for regulators.

This is the 3.11.7 stable release

This is the 3.10.18 stable release

This is the 3.4.68 stable release

Linux 3.12

sound fixes #2 for 3.12-final

The fixes for random bugs that have been reported lately in the game:
a few fixes in ASoC dpam and wm_hubs bugs spotted by Coverity, a
one-liner HD-audio fixup, and a fix for Oops with DPCM.

They are not so critically urgent bugs, but all small and safe.

Linux 3.12-rc7

This is the 3.2.52 stable release

This is the 3.4.67 stable release

This is the 3.0.101 stable release

Linux 3.12-rc6

This is the 3.11.6 stable release

This is the 3.10.17 stable release

regulator: Allow supplies to be aliased

Provide an interface for devices to map their supplies elsewhere, mainly
for MFDs to handle their subdevices.

Three GPIO fixes for the v3.12 series:
- A fix to the Lynxpoint IRQ handler
- Two late fixes to fallout from the gpiod refactoring

This is the 3.11.5 stable release

This is the 3.10.16 stable release

This is the 3.4.66 stable release
