sound fixes for 4.4

A slightly higher volume than a new year's wish, but not too
worrisome: a large LOC is only for HD-audio device-specific quirks,
so fairly safe to apply.  The rest ASoC fixes are all trivial and
small; a simple replacement of mutex call with nested lock version,
a few Arizona and Realtek codec fixes, and a regression fix for
Skylake firmware handling.

sound fixes for 4.4-rc7

This shouldn't be a nightmare before Christmas: just a handful
small device-specific fixes for various ASoC and HD-audio drivers.
Most of them are stable fixes.

Linux 4.4-rc6

- fix atomic watermark recomputation logic (Maarten)
- modeset sequence fixes for LPT (Ville)
- more kbl enabling&prep work (Rodrigo, Wayne)
- first bits for mst audio
- page dirty tracking fixes from Dave Gordon
- new get_eld hook from Takashi, also included in the sound tree
- fixup cursor handling when placed at address 0 (Ville)
- refactor VBT parsing code (Jani)
- rpm wakelock debug infrastructure ( Imre)
- fbdev is pinned again (Chris)
- tune the busywait logic to avoid wasting cpu cycles (Chris)

sound fixes for 4.4-rc6

As usual in rc6, this update contains only a few HD-audio and
USB-audio device-specific quirks: yet another Thinkpad noise fixes,
Dell headphone mic fixes, and AudioQuest DragonFly fixes.

Linux 4.4-rc5

Add get_eld audio component for i915/HD-audio

Here are the patchset to add get_eld op to audio component for
communicating more directly between i915 and HD-audio.

Currently, the HDMI/DP audio status and ELD are notified and obtained
via the hardware-level communication over HD-audio unsolicited event
and verbs although the graphics driver holds the exactly same
information.  As we already have a notification via audio component,
this is another step forward; namely, the audio driver may fetch
directly the audio status and ELD via the new component op.

The commits are based on Dave's latest drm-next branch.

sound fixes for 4.4-rc5

Again less intensive changes in this rc: you can find only a few
HD-audio fixes (noise fixes for Intel Broxton chip and a few Thinkpad
models, quirks for Alienware 17 and Packard Bell DOTS) in addition
to a long-standing rme96 bug fix.

This is the "fix igt basic test set issues" edition.
- more PSR fixes from Rodrigo, getting closer
- tons of fifo underrun fixes from Ville
- runtime pm fixes from Imre, Daniel Stone
- fix SDE interrupt handling properly (Jani Nikula)
- hsw/bdw fdi modeset sequence fixes (Ville)
- "don't register bad VGA connectors and fall over" fixes (Ville)
- more fbc fixes from Paulo
- and a grand total of exactly one feature item: Implement dma-buf/fence based
  cross-driver sync in the i915 pageflip path (Alex Goins)

Linux 4.4-rc4

sound fixes for 4.4-rc4

This time we've got a larger number of updates, mainly from ASoC
world.  The only significant LOCs found here are for Realtek codecs,
where most of changes are quite systematic replacements.

There are also a few fixes in ASoC core side: one is the PM call order
fix to ensure the DPAM resume working properly.  Another is the proper
cleanup call after freeing DAPM widgets, and the correction of the
wrong callback set in topology API.

The rest are a wide range of driver-specific small fixes, including
HD-audio.

Linux 4.4-rc3

sound fixes for 4.4-rc3

Here are no big surprises but just all small fixes, mostly
device-specific quirks for HD-audio and USB-audio:
- Fix for detection of FireWire DICE Loud devices
- Intel Broxton HDMI/DP PCI IDs and relevant quirks
- Noise fixes: Dell XPS13 2015 model, Dell Latitude E6440, Gigabyte
  Z170X mobo
- Fix the headphone mixer assignment on HP laptops for PulseAudio
- USB-MIDI fixes for Medeli DD305 and CH345
- Apply fixup for Acer Aspire One Cloudbook 14

4 weeks because of my vacation, so a bit more:
- final bits of the typesafe register mmio functions (Ville)
- power domain fix for hdmi detection (Imre)
- tons of fixes and improvements to the psr code (Rodrigo)
- refactoring of the dp detection code (Ander)
- complete rework of the dmc loader and dc5/dc6 handling (Imre, Patrik and
  others)
- dp compliance improvements from Shubhangi Shrivastava
- stop_machine hack from Chris to fix corruptions when updating GTT ptes on bsw
- lots of fifo underrun fixes from Ville
- big pile of fbc fixes and improvements from Paulo
- fix fbdev failures paths (Tvrtko and Lukas Wunner)
- dp link training refactoring (Ander)
- interruptible prepare_plane for atomic (Maarten)
- basic kabylake support (Deepak&Rodrigo)
- don't leak ringspace on resets (Chris)

linux-kselftest-4.4-rc3

This update consists of one minor documentation fix and a fix
to an existing test.

Linux 4.4-rc2

Linux 4.4-rc1

sound fixes for 4.4-rc1

Here are a collection of small fixes tha have been gathered for
4.4-rc1.  The only significant changes are those in PCI drivers
Kconfig, to use "depends on" instead of "select" for CONFIG_ZONE_DMA.
A reverse select is often more user-friendly, but in this case, it
makes hard to manage with the conflict with ZONE_DEVICE, so changed in
such a way for now.

Others are all small fixes and quirks: an error check in soundcore
reigster_chrdev(), HD-audio HDMI/DP phantom jack fix, Intel Broxton DP
quirk, USB-audio DSD device quirk, some constifications, etc.
