Linux 4.5-rc6

sound fixes for 4.5-rc6

Things got calmed down for rc6, as it seems, and we have only a few
HD-audio fixes at this time: a fix for Skylake codec probe errors,
a fix for missing interrupt handling, and a few Dell and HP quirks.

Linux 4.5-rc5

sound fixes for 4.5-rc5

this update contains again a few more fixes for ALSA core stuff
although it's no longer high flux: two race fixes in sequencer and one
PCM race fix for non-atomic PCM ops.  In addition, HD-audio gained a
similar fix for race at reloading the driver.

- lots and lots of fbc work from Paulo
- max pixel clock checks from Mika Kahola
- prep work for nv12 offset handling from Ville
- piles of small fixes and refactorings all around

Linux 4.5-rc4

another sound fix for 4.5-rc4

This contains the last-minute fix for the double-free of usb-audio
MIDI device at probe failure.

sound fixes for 4.5-rc4

In this rc, we've got more volume than previous rc, unsurprisingly;
the majority of updates in ASoC are about Intel drivers, and another
major changes are the continued plumbing of ALSA timer bugs revealed
by syzkaller fuzzer.  Hopefully both settle down now.

Other than that, HD-audio received a couple of code fixes as well as
the usual quirks, and various small fixes are found for FireWire
devices, ASoC codecs and drivers.

Linux 4.5-rc3

sound fixes for 4.5-rc3

This was a busy week and I had to prepare a pile of duct tapes for
the bugs reported by syzkaller fuzzer in wide range of ALSA core
APIs: timer, rawmidi, sequencer, and PCM OSS emulation.  Let's see
how many other holes we need to plug.

Besides that, a few usual boring stuff, HD- and USB-audio quirks,
have been added.

Linux 4.5-rc2

sound fixes for 4.5-rc2

There are a few fixes in ALSA core for bugs that have been spotted by
fuzzer.  Also a temporary workaround for PowerPC (and possibly other)
builds with incompatible ioctls was applied to compress API.

Other than that, a few trivial fixes and quirks for FireWire BeBoB,
USB-audio and HD-audio are found, too.

- support for v3 vbt dsi blocks (Jani)
- improve mmio debug checks (Mika Kuoppala)
- reorg the ddi port translation table entries and related code (Ville)
- reorg gen8 interrupt handling for future platforms (Tvrtko)
- refactor tile width/height computations for framebuffers (Ville)
- kerneldoc integration for intel_pm.c (Jani)
- move default context from engines to device-global dev_priv (Dave Gordon)
- make seqno/irq ordering coherent with execlist (Chris)
- decouple internal engine number from UABI (Chris&Tvrtko)
- tons of small fixes all over, as usual

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
