Merge tag 'sound-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "Most of changes at this time are for ASoC, spread over ASoC core and
  drivers due to the API prefix standardization.

  Other than that, there have little change wrt API, rather lots of
  driver-specific updates and fixes.

  Some highlight below:

  ASoC:
   - Standardization of API prefix
   - GPIO API usage improvements
   - Support for HDA patches
   - Lots of work on SOF, including crash dump support
   - Fixes for noise when stopping some Sounwire CODECs
   - Support for AMD platforms with es83xx, AMD ACP 6.3 and 7.0, Awinc
     AT87390 and AW88399, many Intel platforms, many Mediatek platforms,
     Qualcomm SM6115 and SC7180 platforms, Richtek RTQ9128 and Texas
     Instruments TAS575x

  HD-audio and USB-audio:
   - Deferred probe support of audio component binding
   - More fixes and enhancements for Cirrus subcodecs
   - USB Scarlett2 mixer and McIntosh DSD quirk

  Others:
   - More enhancement of snd-aloop driver
   - Update MAINTAINERS entry for linux-sound mailing list"
