Merge tag 'sound-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "The majority of works in this cycle are about ASoC spread over trees.
  Most of them are for new devices and cleanups / refactoring works, and
  not much significant changes are seen in the core side.

  Below are some highlights:

  ASoC:

   - Continued refactoring to move into common helper functions

   - Lots of DT schema conversons and stylistic nits

   - Continued work on building out the new SOF IPC4 scheme

   - Continued work for Intel AVS

   - New drivers for Awinc AT88395, Infineon PEB2466, Iron Device
     SMA1303, Mediatek MT8188, Realtek RT712, Renesas IDT821034,
     Samsung/Tesla FSD SoC I2S, and TI TAS5720A-Q1

  ALSA:

   - A few cleanups to make the remove callbacks to void returns

   - FireWire refactoring and enhancements

   - PCM kselftest enhancements"
