Merge tag 'sound-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "Not much dramatic changes at this time, but we've received quite a lot
  of changes for ASoC, while there are still a few fixes and quirks for
  usual HD- and USB-auido. Here are some highlights.

  ASoC:

   - Overhaul of endianness specification for data formats, avoiding
     needless restrictions due to CODECs

   - Initial stages of Intel AVS driver merge

   - Introduction of v4 IPC mechanism for SOF

   - TDM mode support for AK4613

   - Support for Analog Devices ADAU1361, Cirrus Logic CS35L45, Maxim
     MAX98396, MediaTek MT8186, NXP i.MX8 micfil and SAI interfaces,
     nVidia Tegra186 ASRC, and Texas Instruments TAS2764 and TAS2780

  Others:

   - A few regression fixes after the USB-audio endpoint management
     refactoring

   - More enhancements for Cirrus HD-audio codec support (still ongoing)

   - Addition of generic serial MIDI driver"
