Merge tag 'sound-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "This became again a busy development cycle.  There are few ALSA core
  updates (merely API cleanups and sparse fixes), with the majority of
  other changes are found in ASoC scene.

  Here are some highlights:

  ALSA core:
   - More helper macros for sparse warning fixes (e.g. bitwise types)
   - Slight optimization of PCM OSS locks
   - Make common handling for PCM / compress buffers (for SOF)

  ASoC:
   - Lots of code refactoring and modernization for (still ongoing)
     componentization works
   - Conversion of SND_SOC_ALL_CODECS to use imply
   - Continued refactoring and fixing of the Intel SOF/SST support,
     including the initial (but still incomplete) SoundWire support
   - SoundWire and more advanced clocking support for Realtek RT5682
   - Support for amlogic GX, Meson 8, Meson 8B and T9015 DAC, Broadcom
     DSL/PON, Ingenic JZ4760 and JZ4770, Realtek RL6231, and TI TAS2563
     and TLV320ADCX140

  HD-audio:
   - Optimizations in HDMI jack handling
   - A few new quirks and fixups for Realtek codecs

  USB-audio:
   - Delayed registration support
   - New quirks for Motu, Kingston, Presonus"
