Merge tag 'sound-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "There are little changes in core part, but lots of development are
  found in drivers, especially ASoC.  The diffstat shows regmap-related
  changes for a slight API additions / changes, and that's all.

  Looking at the code size statistics, the most significant addition is
  for Intel Skylake.  (Note that SKL support is still underway, the
  codec driver is missing.) Also STI controller driver is a major
  addition as well as a few new codec drivers.

  In HD-audio side, there are fewer changes than the past.  The
  noticeable change is the support of ELD notification from i915
  graphics driver.  Thus this pull request carries a few changes in
  drm/i915.

  Other than that, USB-audio got a rewrite of runtime PM code.  It was
  initiated by lockdep warning, but resulted in a good cleanup in the
  end.

  Below are the highlights:

  Common:
   - Factoring out of AC'97 reset code from ASoC into the core helper
   - A few regmap API extensions (in case it's not pulled yet)

  ASoC:
   - New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
     RT298 and ST STI controllers
   - Machine drivers for Rockchip systems with MAX98090 and RT5645 and
     RT5650
   - Initial driver support for Intel Skylake devices
   - Lots of rsnd cleanup and enhancements
   - A few DAPM fixes and cleanups
   - A large number of cleanups in various drivers (conversion and
     standardized to regmap, component) mostly by Lars-Peter and Axel

  HD-audio:
   - Extended HD-audio core for Intel Skylake controller support
   - Quirks for Dell headsets, Alienware 15
   - Clean up of pin-based quirk tables for Realtek codecs
   - ELD notifier implenetation for Intel HDMI/DP

  USB-audio:
   - Refactor runtime PM code to make lockdep happier"
