Merge tag 'sound-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "At this time, it's an interesting mixture of changes for both old and
  new stuff. Majority of changes are about ASoC (lots of systematic
  changes for converting remove callbacks to void, and cleanups), while
  we got the fixes and the enhancements of very old PCI cards, too.

  Here are some highlights:

  ALSA/ASoC Core:
   - Continued effort of more ASoC core cleanups
   - Minor improvements for XRUN handling in indirect PCM helpers
   - Code refactoring of PCM core code

  ASoC:
   - Continued feature and simplification work on SOF, including
     addition of a no-DSP mode for bringup, HDA MLink and extensions to
     the IPC4 protocol
   - Hibernation support for CS35L45
   - More DT binding conversions
   - Support for Cirrus Logic CS35L56, Freescale QMC, Maxim MAX98363,
     nVidia systems with MAX9809x and RT5631, Realtek RT712, Renesas
     R-Car Gen4, Rockchip RK3588 and TI TAS5733

  ALSA:
   - Lots of works for legacy emu10k1 and ymfpci PCI drivers
   - PCM kselftest fixes and enhancements"
