Linux 4.5-rc1

sound fixes for 4.5-rc1

Here are lots of small fixes that have been collected since the
previous pull.  This time, not only trivial ones but fixes for some
serious bugs are included:
- Fix for CPU lockups by snd-hrtimer accesses
- Fix for unsafe disconnection handling in ALSA timer code
- Fix for Oops due to race at HD-audio module removal
- Fixes for possible memory corruption via 32bit PCM and sequencer
  compat ioctls
- Fix for regression in HD-audio generic model handling
- Suppress kernel warnings for invalid TLV ioctls that may flood up
- Fix the missing SSC clock handling for at73c213
- A pin fixup for ASUS N550JX

sound updates for 4.5-rc1

We've had quite busy weeks in this cycle.  Looking at ALSA core, the
significant changes are a few fixes wrt timer and sequencer ioctls
that have been revealed by fuzzer recently.  Other than that, ASoC
core got a few updates about DAI link handling, but these are rather
straightforward refactoring.

In drivers scene, ASoC received quite lots of new drivers in addition
to bunch of updates for still ongoing Intel Skylake support and
topology API.  HD-audio gained a new HDMI/DP hotplug notification via
component.  FireWire got a pile of code refactoring/updates with
SCS.1x driver integration.

More highlights are shown below.

[NOTE: this contains also many commits for DRM.  This is due to the
 pull of drm stable branch into sound tree, as the base of i915 audio
 component work for HD-audio.  The highlights below don't contain
 these DRM changes, as these are supposed to be pulled via drm tree in
 anyway sooner or later.]

Core
 - Handful fixes to harden ALSA timer and sequencer ioctls against
   races reported by syzkaller fuzzer
 - Irq description string can be unique to each card; only for
   HD-audio for now

ASoC
 - Conversion of the array of DAI links to a list for supporting
   dynamically adding and removing DAI links
 - Topology API enhancements to make everything more component based
   and being able to specify PCM links via topology
 - Some more fixes for the topology code, though it is still not final
   and ready for enabling in production; we really need to get to the
   point where that can be done
 - A pile of changes for Intel SkyLake drivers which hopefully deliver
   some useful initial functionality for systems with this chipset,
   though there is more work still to come
 - Lots of new features and cleanups for the Renesas drivers
 - ANC support for WM5110
 - New drivers: Imagination Technologies IPs, Atmel class D speaker,
   Cirrus CS47L24 and WM1831, Dialog DA7128, Realtek RT5659 and
   RT56156, Rockchip RK3036, TI PC3168A, and AMD ACP
 - Rename PCM1792a driver to be generic pcm179x

HD-Audio
 - Use audio component for i915 HDMI/DP hotplug handling
 - On-demand binding with i915 driver
 - bdl_pos_adj parameter adjustment for Baytrail controllers
 - Enable power_save_node for CX20722; this shouldn't lead to
   regression, hopefully
 - Kabylake HDMI/DP codec support
 - Quirks for Lenovo E50-80, Dell Latitude E-series, and other Dell
   machines
 - A few code refactoring

FireWire
 - Lots of code cleanup and refactoring
 - Integrate the support of SCS.1x devices into snd-oxfw driver;
   snd-scs1x driver is obsoleted

USB-audio
 - Fix possible NULL dereference at disconnection
 - A regression fix for Native Instruments devices

Misc
 - A few code cleanups of fm801 driver

- GuC ADS support (Alex Dai)
- support for v3 of the vbt mipi/dsi panel sequence (Jani Nikula)
- more prep work for atomic watermarks (Matt Roper)
- clean up cursor handling and align more with other planes (Maarten)
- improvements to the unclaimed mmio debug code (Mika Kuoppalla)
- various improvements, w/a, updated translation tables, ...

Linux 4.4

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.

Linux 4.4-rc8

Linux 4.4-rc7

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.
