Merge tag 'sound-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
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"
