GPIO fixes for the v4.6 series:
- Prevent NULL dereference in the Xgene driver
- Fix an uninitialized spinlock in the menz127 driver

- VBT code refactor for a clean split between parsing&using of firmware
  information (Jani)
- untangle the pll computation code, and splitting up the monster
  i9xx_crtc_compute_clocks (Ander)
- dsi support for bxt (Jani, Shashank Sharma and others)
- color manager (i.e. de-gamma, color conversion matrix & gamma support) from
  Lionel Landwerlin
- Vulkan hsw support in the command parser (Jordan Justen)
- large-scale renaming of intel_engine_cs variables/parameters to avoid the epic
  ring vs. engine confusion introduced in gen8 (Tvrtko Ursulin)
- few atomic patches from Maarten&Matt, big one is two-stage wm programming on ilk-bdw
- refactor driver load and add infrastructure to inject load failures for
  testing, from Imre
- various small things all over

Linux 4.6-rc1

Android Wear 6.0.1 Release 0.20

sound fixes for 4.6-rc1

The previous pull request introduced a few WARN_ON() for Intel
HD-audio HDMI.  Indeed it caught bugs, and now users get annoyed.
So this request came up: a collection of small fixes to paper over
the inconsistencies on (mostly) old Intel chipsets.

In addition, a trivial USB-audio quirk is included, too.

This is the 3.4.111 stable release

DeviceTree updates for 4.6:

- New tool dtx_diff to diff DT files.

- Sync kernel's dtc/libfdt to current dtc repo master.

- Fix for reserved memory regions located in highmem.

- Document standard unit suffixes for DT properties.

- Various DT binding doc updates.

This is the 3.12.57 stable release

sound updates for 4.6-rc1

After a heavy storm by syzkaller in 4.5 cycle, we have relatively few
changes in the core at this time while a lot of changes are found in
the driver side, unsurprisingly.  Below are some highlights:

ALSA core:
- A few more hardening in ALSA timer codes
- An extension of sequencer API for advertising the card / pid
- Small fixes in compress-offload and jack layers

HD-audio:
- Dynamic PCM assignment in HDMI/DP codec; preparation for upcoming
  DP-MST support
- Lots of code refactoring for sharing with ASoC SKL driver
- Regression fixes for Intel HDMI/DP
- Fixups for CX20724 codec, Lenovo AiO

USB-audio:
- Add quirk_alias option to make quirk debugging easier
- Fixes for possible Oops by malformed firmware

Firewire:
- Add support for FW-1804 in tascam driver
- Improvements / changes in card registration, multi stream handling,
  etc for DICE
- Lots of code refactoring

ASoC:
- Enhancements of still ongoing topology API
- Lots of commits for Intel Skylake support including HDMI support
- A few Intel Atom driver updates for recent devices
- Lots of improvements to the Renesas drivers
- Capture support for Qualcomm drivers
- Support for TI DaVinci DRA7xxx devices
- New machine drivers for Freescale systems with Cirrus CODECs,
  Mediatek systems with RT5650 CODECs
- New CPU drivers for Allwinner S/PDIF controllers
- New CODEC drivers for Maxim MAX9867 and MAX98926 and Realtek RT5514

Linux 4.1.20

Linux 3.18.29

This is the bulk of GPIO changes for kernel v4.6:

Core changes:

- The gpio_chip is now a *real device*. Until now the gpio chips
  were just piggybacking the parent device or (gasp) floating in
  space outside of the device model. We now finally make GPIO chips
  devices. The gpio_chip will create a gpio_device which contains
  a struct device, and this gpio_device struct is kept private.
  Anything that needs to be kept private from the rest of the kernel
  will gradually be moved over to the gpio_device.

- As a result of making the gpio_device a real device, we have added
  resource management, so devm_gpiochip_add_data() will cut down on
  overhead and reduce code lines. A huge slew of patches convert
  almost all drivers in the subsystem to use this.

- Building on making the GPIO a real device, we add the first step
  of a new userspace ABI: the GPIO character device. We take small
  steps here, so we first add a pure *information* ABI and the tool
  "lsgpio" that will list all GPIO devices on the system and all
  lines on these devices. We can now discover GPIOs properly from
  userspace. We still have not come up with a way to actually *use*
  GPIOs from userspace.

- To encourage people to use the character device for the future,
  we have it always-enabled when using GPIO. The old sysfs ABI is
  still opt-in (and can be used in parallel), but is marked as
  deprecated. We will keep it around for the foreseeable future,
  but it will not be extended to cover ever more use cases.

Cleanup:

- Bjorn Helgaas removed a whole slew of per-architecture <asm/gpio.h>
  includes. This dates back to when GPIO was an opt-in feature and
  no shared library even existed: just a header file with proper
  prototypes was provided and all semantics were up to the arch to
  implement. These patches make the GPIO chip even more a proper
  device and cleans out leftovers of the old in-kernel API here
  and there. Still some cruft is left but it's very little now.

- There is still some clamping of return values for .get() going
  on, but we now return sane values in the vast majority of drivers
  and the errorpath is sanitized. Some patches for powerpc, blackfin
  and unicore still drop in.

- We continue to switch the ARM, MIPS, blackfin, m68k local GPIO
  implementations to use gpiochip_add_data() and cut down on code
  lines.

- MPC8xxx is converted to use the generic GPIO helpers.

- ATH79 is converted to use the generic GPIO helpers.

New drivers:

- WinSystems WS16C48

- Acces 104-DIO-48E

- F81866 (a F7188x variant)

- Qoric (a MPC8xxx variant)

- TS-4800

- SPI serializers (pisosr): simple 74xx shift registers connected
  to SPI to obtain a dirt-cheap output-only GPIO expander.

- Texas Instruments TPIC2810

- Texas Instruments TPS65218

- Texas Instruments TPS65912

- X-Gene (ARM64) standby GPIO controller
