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"
