Merge tag 'sound-4.21-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "There are no intensive changes in both ALSA and ASoC core parts while
  rather most of changes are a bunch of driver fixes and updates. A
  large diff pattern appears in ASoC TI part which now merges both OMAP
  and DaVinci stuff, but the rest spreads allover the places.

  Note that this pull request includes also some updates for LED trigger
  and platform drivers for mute LEDs, appearing in the diffstat as well.

  Some highlights:

  ASoC:
   - Preparatory work for merging the audio-graph and audio-graph-scu
     cards
   - A merge of TI OMAP and DaVinci directories, as both product lines
     get merged together. Also including a few architecture changes as
     well.
   - Major cleanups of the Maxim MAX9867 driver
   - Small fixes for tablets & co with Intel BYT/CHT chips
   - Lots of rsnd updates as usual
   - Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with
     RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx
     I2S controllers

  HD-audio:
   - Introduce audio-mute LED trigger for replacing the former hackish
     dynamic binding
   - Huawei WMI hotkey and mute LED support
   - Refactoring of PM code and display power controls
   - Headset button support in the generic jack code
   - A few updates for Tegra
   - Fixups for HP EliteBook and ASUS UX391UA
   - Lots of updates for Intel ASoC HD-audio, including the improved DSP
     detection and the fallback binding from ASoC SST to legacy HD-audio
     controller drivers

  Others:
   - Updates for FireWire TASCAM and Fireface devices, some other fixes
   - A few potential Spectre v1 fixes that are all trivial"
