Pull sound updates from Takashi Iwai:
 "As the diffstat scatters over the tree, we've got many tree-wide small
  changes, but also got quite a few intrusive changes in the core side.
  The only ABI-visible core change is the new rawmidi framing mode
  support while others are kernel-internal, mostly code refactoring
  and/or nice improvements.

  Here are some highlights:

  Core:
   - A new framing access mode for rawmidi to get timestamps
   - Cleanup / refactoring of buffer memory management helper code
   - Support for automatic negotiation of ASoC DAI formats
   - Revival of software suspend for PCM and control core, as a
     preliminary work for PCI BAR rescan support

  ASoC:
   - Accessory detection support for several Qualcomm parts
   - Support for IEC958 control with hdmi-codec
   - Merging of Tegra machine drivers into a single driver
   - Support for AmLogic SM1 TOACODEC, Intel AlderLake-M, several NXP
     i.MX8 variants, NXP TFA1 and TDF9897, Rockchip RK817, Qualcomm
     Quinary MI2S, Texas Instruments TAS2505

  USB-audio:
   - Reduction of latency at playback start
   - Code cleanup / fixes of usx2y driver
   - Scarlett2 mixer code fixes and enhancements
   - Quirks for Ozone and Denon devices

  HD-audio:
   - A few quirks for HP and ASUS machines
   - Display power management fixes

  Others:
   - FireWire code refactoring and enhancements
   - Tree-wide trivial coding-style fixes"
