Merge tag 'sound-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "There are a few intensive changes in ALSA core side at this time that
  helped with significant code reduction. Meanwhile we keep getting new
  stuff, so the total size still grows...

  Anyway, the below are some highlights in this development cycle.

  ALSA core:

   - New helpers to manage page allocations and card object with devres

   - Refactoring for memory allocation with wc-pages

   - A new PCM hardware flag SNDRV_PCM_INFO_EXPLICIT_SYNC for
     controlling the explicit sync of the stream control; it'll be used
     for ASoC SOF and non-coherent memory in future

  ASoC:

   - Lots of cleanups and improvements to the Intel drivers, including
     some new systems support

   - New support for AMD Vangoh, CUI CMM-4030D-261, Mediatek Mt8195,
     Renesas RZ/G2L Mediatek Mt8195, RealTek RT101P, Renesas RZ/G2L,
     Rockchip RK3568 S/PDIF

  USB-audio:

   - Re-organized the quirk handling and a new option quirk_flags

   - Fix for a regression in 5.14 code change for JACK

   - Quirks for Sony WALKMAN, Digidesign mbox

  HD-audio:

   - Enhanced support for CS8409 codec

   - More consistent shutdown behavior with the runtime PM

   - The model option can accept the PCI or codec SSID as an alias

   - Quirks for ASUS ROG, HP Spectre x360

  Others:

   - Lots of code reduction in legacy drivers with devres helpers

   - FireWire MOTU 896HD support"
