Merge tag 'sound-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "Lots of changes (slightly more code increase than usual) at this time,
  while most of code changes are ASoC driver-specific.

  Here are some highlights:

  Core:

   - The new auxiliary bus implementation for Intel DSP, which will be
     used by other drivers as well

   - Lots of ASoC core cleanups and refactoring

   - UBSAN and KCSAN fixes in rawmidi, sequencer and a few others

   - Compress-offload API enhancement for the pause during draining

  HD- and USB-audio:

   - Enhancements of the USB-audio implicit feedback support, including
     better full-duplex operations

   - Continued CA0132 improvements and fixes

   - A few new quirk entries, HDMI audio fixes

  ASoC:

   - Support for boot time selection of Intel DSP firmware, which should
     help distros/users testing new stuff more easily; the kconfig was
     moved to boot time option, too

   - Some basic DPCM support in audio graph card

   - Removal of old pre-DT Freescale drivers

   - Support for Allwinner H6 I2S, Analog Devices ADAU1372, Intel
     Alderlake-S, GMediatek MT8192, NXP i.MX HDMI and XCVR, Realtek
     RT715, Qualcomm SM8250 and simple GPIO based muxes"
