IOMMU Updates for Linux v4.8

In the updates:

	* Big endian support and preparation for defered probing for the
	  Exynos IOMMU driver

	* Simplifications in iommu-group id handling

	* Support for Mediatek generation one IOMMU hardware

	* Conversion of the AMD IOMMU driver to use the generic IOVA
	  allocator. This driver now also benefits from the recent
	  scalability improvements in the IOVA code.

	* Preparations to use generic DMA mapping code in the Rockchip
	  IOMMU driver

	* Device tree adaption and conversion to use generic page-table
	  code for the MSM IOMMU driver

	* An iova_to_phys optimization in the ARM-SMMU driver to greatly
	  improve page-table teardown performance with VFIO

	* Various other small fixes and conversions

regulator: Updates for v4.8

A quiet regulator API release, a few new drivers and some fixes but
nothing too notable.  There will also be some updates for the PWM
regulator coming through the PWM tree which provide much smoother
operation when taking over an already running PWM regulator after boot
using some new PWM APIs.

 - Support for configuration of the initial suspend state from DT.
 - New drivers for Mediatek MT6323, Ricoh RN5T567 and X-Powers AXP809.

ASoC: Updates for v4.8

Not really any framework work this time around (though we have seen one
of the Analog Devices drivers move more to the clock API which is good
to see) but rather a lot of new drivers:

 - Lots of updates for the Intel drivers, mostly board support and bug
   fixing, and to the NAU8825 driver.
 - Work on generalizing bits of simple-card to allow more code sharing
   with the Renesas rsrc-card (which can't use simple-card due to DPCM).
 - Removal of the Odroid X2 driver due to replacement with simple-card.
 - Support for several new Mediatek platforms and associated boards.
 - New drivers for Allwinner A10, Analog Devices ADAU7002, Broadcom
   Cygnus, Cirrus Logic CS35L33 and CS53L30, Maxim MAX8960 and MAX98504,
   Realtek RT5514 and Wolfson WM8758

media updates for v4.8-rc1

This is the bulk of GPIO changes for the v4.8 kernel cycle.

Core changes:

- The big item is of course the completion of the character
  device ABI. It has now replaced and surpassed the former
  unmaintainable sysfs ABI: we can now hammer (bitbang)
  individual lines or sets of lines and read individual lines
  or sets of lines from userspace, and we can also register
  to listen to GPIO events from userspace. As a tie-in we
  have two new tools in tools/gpio: gpio-hammer and
  gpio-event-mon that illustrate the proper use of the new
  ABI. As someone said: the wild west days of GPIO are now
  over.

- Continued to remove the pointless
  ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB Kconfig symbols.
  I'm patching hexagon, openrisc, powerpc, sh, unicore,
  ia64 and microblaze. These are either ACKed by their
  maintainers or patched anyways after a grace period and
  no response from maintainers. Some archs (ARM) come in from
  their trees, and others (x86) are still not fixed, so I
  might send a second pull request to root it out later in
  this merge window, or just defer to v4.9.

- The GPIO tools are moved to the tools build system.

New drivers:

- New driver for the MAX77620/MAX20024.

- New driver for the Intel Merrifield.

- Enabled PCA953x for the TI PCA9536.

- Enabled PCA953x for the Intel Edison.

- Enabled R8A7792 in the RCAR driver.

Driver improvements:

- The STMPE and F7188x now supports the .get_direction()
  callback.

- The Xilinx driver supports setting multiple lines at
  once.

- ACPI support for the Vulcan GPIO controller.

- The MMIO GPIO driver supports device tree probing.

- The Acer One 10 is supported through the _DEP ACPI
  attribute.

Cleanups:

- A major cleanup of the OF/DT support code. It is way
  easier to read and understand now, probably this improves
  performance too.

- Drop a few redundant .owner assignments.

- Remove CLPS711x boardfile support: we are 100% DT.

- more engine code unification (Tvrtko)
- reorganize rps&rc6 setup (Chris Wilson)
- hotplug polling when in deep rpm states, especially fixes vls (Lyude)
- mocs fix for bxt (Imre)
- convert i915 request to use dma fences (Chris)
- prep work for lockless i915 requests/fences (needed for full sync integration)
  from Chris Wilson
- wait for external rendering/fences attached to dma_bufs (Chris)
- tons of small bugfixes all over

Linux 4.7

sound fixes #2 for 4.7-final

Now one more regression fix in addition to the previous pull request:
two changes in the core part are for unusual error paths, while the
rest are the regular HD-audio fixes and one USB-audio regression fix.

Compile problem fix for Tegra

This is the 3.12.62 stable release

qcomlt-v4.7-rc7

qcomlt-v4.6

Allwinner DT changes for 4.8, take 2

Another set of changes for the 4.8 merge window, among which:
  - Reworking of the DT for the tablets based on Allwinner reference design
    and q8 designs to avoid duplication as much as possible
  - Renaming a DT merged in the first PR for consistency
  - Enable a few devices on some boards
  - New boards: Polaroid MID2407PXE03, inet86dz
