Merge tag 'sound-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "This is a relatively calm cycle, and majority of changes are about ASoC. There are little changes in the core side but we received lots of new drivers for new vendors. ALSA Core: - The new accel operation mode for compress-offload API; only the core part, the actual user will follow later ASoC: - Continued API simplification works - Renaming of the sh directory to Renesas - Factoring out of some of the common code for Realtek devices - Ussal ASoC Intel SOF, AMD and SoundWire updates - Support for Allwinner H616, AMD ACP 6.3 systems, AWInic AW88081, Cirrus Logic CS32L84, Everest ES8328, Iron Devices SMA1307, Longsoon I2S, NeoFidelity NTP8918 and NTP8835, Philips UDA1342, Qualcomm SM8750, RealTek RT721, and ST Microelectronics STM32MP25 HD- and USB-audio: - Clean up of IRQ handling in legacy HD-audio driver - Fix soft lockup at disconnection of non-standard USB drivers - Scarlett2 mixer improvements - New quirks and cleanups in HD- and USB-audio" * tag 'sound-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (278 commits) ALSA: hda: Poll jack events for LS7A HD-Audio ASoC: hdmi-codec: reorder channel allocation list ALSA: ump: Fix the wrong format specifier ASoC: Intel: soc-acpi-intel-lnl-match: add rt712_vb + rt1320 support ASoC: stm32: dfsdm: change rate upper limits ASoC: sma1307: fix uninitialized variable refence ASoC: dt-bindings: simple-mux: add idle-state property ASoc: simple-mux: add idle-state support ASoC: sdca: test adev before calling acpi_dev_for_each_child ASoC: SOF: ipc4-topology: remove redundant assignment to variable ret ASoC: amd: ps: fix the pcm device numbering for acp 6.3 platform ASoC: amd: acp: add soundwire machine driver for legacy stack ASoC: amd: acp: move get_acp63_cpu_pin_id() to common file ASoC: amd: ps: add soundwire machines for acp6.3 platform ASoC: amd: acp: add RT711, RT714 & RT1316 support for acp 6.3 platform ASoC: amd: acp: add rt722 based soundwire machines ALSA: compress_offload: Add missing descriptions in structs ALSA: 6fire: Release resources at card release ALSA: caiaq: Use snd_card_free_when_closed() at disconnection ALSA: us122l: Drop mmap_count field ...
