ASoC: Fix for v4.7

Fix an unused variable warning in the HDAC code.

This is the bulk of GPIO changes for kernel cycle v4.7:

Core infrastructural changes:

- Support for natively single-ended GPIO driver stages. This
  means that if the hardware has registers to configure open
  drain or open source configuration, we use that rather than
  (as we did before) try to emulate it by switching the line
  to an input to get high impedance. This is also documented
  throughly in Documentation/gpio/driver.txt for those of you
  who did not understand one word of what I just wrote.

- Start to do away with the unnecessarily complex and
  unitelligible ARCH_REQUIRE_GPIOLIB and
  ARCH_WANT_OPTIONAL_GPIOLIB, another evolutional artifact from
  the time when the GPIO subsystem was unmaintained. Archs can
  now just select GPIOLIB and be done with it, cleanups to
  arches will trickle in for the next kernel. Some minor archs
  ACKed the changes immediately so these are included in this
  pull request.

- Advancing the use of the data pointer inside the GPIO device
  for storing driver data by switching the PowerPC, Super-H
  Unicore and a few other subarches or subsystem drivers in
  ALSA SoC, Input, serial, SSB, staging etc to use it.

- The initialization now reads the input/output state of the
  GPIO lines, so that each GPIO descriptor knows - if this
  callback is implemented - whether the line is input or
  output. This also reflects nicely in userspace "lsgpio".

- It is now possible to name GPIO producer names, line names,
  from the device tree. (Platform data has been supported for
  a while.) I bet we will get a similar mechanism for ACPI
  one of those days. This makes is possible to get sensible
  producer names for e.g. GPIO rails in "lsgpio" in userspace.

New drivers:

- New driver for the Loongson1.

- The XLP driver now supports Broadcom Vulcan ARM64.

- The IT87 driver now supports IT8620 and IT8628.

- The PCA953X driver now supports Galileo Gen2.

Driver improvements:

- MCP23S08 was switched to use the gpiolib irqchip helpers and
  now also suppors level-triggered interrupts.

- 74x164 and RCAR now supports the .set_multiple() callback

- AMDPT was converted to use generic GPIO.

- TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
  support the new single ended callback for open drain
  and in some cases open source.

- Implement the .get_direction() callback for a few more drivers
  like PL061, Xgene.

Cleanups:

- Paul Gortmaker combed through the drivers and de-modularized
  those who are not really modules.

- Move the GPIO poweroff DT bindings to the power subdir where
  they belong.

- Rename gpio-generic.c to gpio-mmio.c, which is much more to the
  point. That's what it is handling, nothing more, nothing less.

regulator: Updates for v4.7

A few core enhancements to deal with some of the slightly more
complicated edge cases that have started cropping up in systems, both
new ones and old ones that people started worrying about upstream, but
otherwise a quiet release for the regulator API:

 - When applying constraints at system image if we have a voltage range
   specified and the regulator is currently configured outside the
   bounds of that range bring the regulator to the nearest end of the
   range.
 - When regulators are in non-regulating bypass modes make sure that we
   always use the voltage from the parent regulator.
 - Support for  LP873x, PV88080, PM8894 and FAN53555 chips.

ASoC: Updates for v4.7

The updates this time around are almost all driver code:

 - Further slow progress on the topology code.
 - Substantial updates and improvements for the da7219, es8328, fsl-ssi
   Intel and rcar drivers.

Linux 4.6

Merge tag 'qcom-soc-for-4.7-2' into net-next

This merges the Qualcomm SOC tree with the net-next, solving the
merge conflict in the SMD API between the two.

media fixes for v4.6-rc8

regulator: Fixes for v4.6

A small collection of driver specific fixes for the regulator
subsysetem:

 - Fix handling of probe deferral for GPIO regulators.
 - Fix a typo in the module alias for DA9053.
 - Fix the definition of BUCK9 in the S2MPS11 driver.  This change looks
   larger than it is because an irregularity in the hardware means that
   the macro used to define bucks 6-10 needs duplicating and tweaking
   to have a separate macro for 9.
 - Fix a series of errors in the definitions of the LDOs the AXP20x
   regulators, some of which had always been present and some of which
   were introduced in the merge window.

Some more work for 4.7, notably:
 * completion and fixups of nla_put_64_64bit() work
 * remove a/b/g/n from wext nickname to avoid confusion
   with 11ac (which wouldn't even fit fully there due to
   string length restrictions)

along with some other minor changes/cleanups.

sound fixes for 4.6

This is a pretty boring pull request as you wish: including a few
small and trivial HD-audio and USB-audio quirks and a couple of small
regression fixes in HD-audio.

This is the 4.4.10 stable release

This is the 3.14.69 stable release

This is the 4.5.4 stable release

Linux 4.1.24

Linux 3.18.33

Allwinner DT changes for 4.7, round 2

Mostly DT patches to enable the new DRM driver on the CHIP, preliminary
support for the A10 and A20, and a support for a new variant of the Olimex
A20-Olinuxino-Lime2 featuring an eMMC
