Pull sound updates from Takashi Iwai:
 "This looks like a relatively calm development cycle; there have been
  only few changes in ALSA and ASoC core sides while we get lots of
  device-specific fixes and updates as usual. Most of commits are about
  ASoC, including Intel SOF/AVS and many device tree updates.

  Below are some highlights:

  Core:
   - Improvement in memalloc helper for fallback allocations
   - More cleanups of ASoC DAPM code

  ASoC:
   - Factoring out of mapping hw_params onto SoundWire configuration
   - The ever ongoing overhauls of the Intel DSP code continue,
     including support for loading libraries and probes with IPC4 on
     SOF.
   - Support for more sample formats on JZ4740
   - Lots of device tree conversions and fixups
   - Support for Allwinner D1, a range of AMD and Intel systems,
     Mediatek systems with multiple DMICs, Nuvoton NAU8318, NXP
     fsl_rpmsg and i.MX93, Qualcomm AudioReach Enable, MFC and SAL,
     RealTek RT1318 and Rockchip RK3588

  ALSA:
   - Addition of PCM kselftest; still minimalistic but can be extended
     in future
   - Fixes for corner-case XRUNs with USB-audio implicit feedback mode
   - Usual device-specific quirk updates for USB- and HD-audio
   - FireWire DICE updates

  This also contains a few cross-tree updates:
   - Some OMAP board file updates for removal of relevant OMAP platforms
   - A new I2C API update for I2C probe API adaption
   - A DRM update for the further hdmi-codec updates"
