Linux 4.6

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.

Linux 4.6-rc7

- refactor stolen quirks to share code between early quirks and i915 (Joonas)
- refactor gem BO/vma funcstion (Tvrtko&Dave)
- backlight over DPCD support (Yetunde Abedisi)
- more dsi panel sequence support (Jani)
- lots of refactoring around handling iomaps, vma, ring access and related
  topics culmulating in removing the duplicated request tracking in the execlist
  code (Chris & Tvrtko) includes a small patch for core iomapping code
- hw state readout for bxt dsi (Ramalingam C)
- cdclk cleanups (Ville)
- dedupe chv pll code a bit (Ander)
- enable semaphores on gen8+ for legacy submission, to be able to have a direct
  comparison against execlist on the same platform (Chris) Not meant to be used
  for anything else but performance tuning
- lvds border bit hw state checker fix (Jani)
- rpm vs. shrinker/oom-notifier fixes (Praveen Paneri)
- l3 tuning (Imre)
- revert mst dp audio, it's totally non-functional and crash-y (Lyude)
- first official dmc for kbl (Rodrigo)
- and tons of small things all over as usual

Linux 4.6-rc6

sound fixes for 4.6-rc6

Usually we get a big collection of fixes for ASoC once during rc.
And this is it.

At this time, most of fixes are about Intel Skylake ASoC driver, which
is a new and still on-going development.  Along with it, a slight
large LOC is seen in legacy HD-audio driver, but it's merely a code
move to the upper layer.

Other than that, the rest are small or trivial fixes to various
drivers, in addition to an ASoC dapm debugfs code fix.

- more userptr cornercase fixes from Chris
- clean up and tune forcewake handling (Tvrtko)
- more underrun fixes from Ville, mostly for ilk to appeas CI
- fix unclaimed register warnings on vlv/chv and enable the debug code to catch
  them by default (Ville)
- skl gpu hang fixes for gt3/4 (Mika Kuoppala)
- edram improvements for gen9+ (Mika again)
- clean up gpu reset corner cases (Chris)
- fix ctx/ring machine deaths on snb/ilk (Chris)
- MOCS programming for all engines (Peter Antoine)
- robustify/clean up vlv/chv irq handler (Ville)
- split gen8+ irq handlers into ack/handle phase (Ville)
- tons of bxt rpm fixes (mostly around firmware interactions), from Imre
- hook up panel fitting for dsi panels (Ville)
- more runtime PM fixes all over from Imre
- shrinker polish (Chris)
- more guc fixes from Alex Dai and Dave Gordon
- tons of bugfixes and small polish all over (but with a big focus on bxt)

Linux 4.6-rc5

sound fixes for 4.6-rc5

Again a relatively calm week without surprise: most of fixes are about
HD-audio, including fixes for Cirrus codec regression and a race over
regmap access.  Although both change are slightly unintuitive, the
risk of further breakage is quite low, I hope.

Other than that, all the rest are trivial.

Linux 4.6-rc4

sound fixes for 4.6-rc4

we've had a very calm development cycle, so far.  Here are the few
fixes for HD-audio and USB-audio, all of which are small and easy.

- make modeset hw state checker atomic aware (Maarten)
- close races in gpu stuck detection/seqno reading (Chris)
- tons&tons of small improvements from Chris Wilson all over the gem code
- more dsi/bxt work from Ramalingam&Jani
- macro polish from Joonas
- guc fw loading fixes (Arun&Dave)
- vmap notifier (acked by Andrew) + i915 support by Chris Wilson
- create bottom half for execlist irq processing (Chris Wilson)
- vlv/chv pll cleanup (Ville)
- rework DP detection, especially sink detection (Shubhangi Shrivastava)
- make color manager support fully atomic (Maarten)
- avoid livelock on chv in execlist irq handler (Chris)

Linux 4.6-rc3

Linux 4.6-rc2

sound fixes for 4.6-rc2

A collection of small fixes:
- A fix in ALSA timer core to avoid possible BUG() trigger
- A fix in ALSA timer core 32bit compat layer
- A few HD-audio quirks for ASUS and HP machines
- AMD HD-audio HDMI controller quirks
- Fixes of USB-audio double-free at some error paths
- A fix for memory leak in DICE driver at hotunplug

- 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

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.

  etc for DICE
