Merge tag 'sound-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"Lots of changes (slightly more code increase than usual) at this time,
while most of code changes are ASoC driver-specific.
Here are some highlights:
Core:
- The new auxiliary bus implementation for Intel DSP, which will be
used by other drivers as well
- Lots of ASoC core cleanups and refactoring
- UBSAN and KCSAN fixes in rawmidi, sequencer and a few others
- Compress-offload API enhancement for the pause during draining
HD- and USB-audio:
- Enhancements of the USB-audio implicit feedback support, including
better full-duplex operations
- Continued CA0132 improvements and fixes
- A few new quirk entries, HDMI audio fixes
ASoC:
- Support for boot time selection of Intel DSP firmware, which should
help distros/users testing new stuff more easily; the kconfig was
moved to boot time option, too
- Some basic DPCM support in audio graph card
- Removal of old pre-DT Freescale drivers
- Support for Allwinner H6 I2S, Analog Devices ADAU1372, Intel
Alderlake-S, GMediatek MT8192, NXP i.MX HDMI and XCVR, Realtek
RT715, Qualcomm SM8250 and simple GPIO based muxes"
