Merge tag 'sound-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "A fairly big update at this time, both in core and driver sides. The core received rewrites in PCM buffer allocation handling and locking optimizations, PCM rate updates followed by lots of cleanups. In ASoC side, the legacy Intel drivers have been deprecated by AVS drivers which leaded to the significant amount of code reduction. SoundWire driver updates and other cleanups contributed more code reduction, too. USB-audio driver received a large cleanup of its big quirk table, and the old snd_print*() API usages in many legacy drivers are replaced with the standard print API. Here are some highlights: Core: - More optimized locking in ALSA control code - Rewrites of memalloc helpers for better DMA API usage - Drop of obsoleted vmalloc PCM buffer helper API - Continued MIDI2 UMP updates - Support of a new user-space driven timer instance - Update for more PCM support rates and cleanups - Xrun counter report in the proc files ASoC: - Continued simplification and cleanup works for ASoC - Extensive cleanups and refactoring of the Soundwire drivers - Removal of Intel machine support obsoleted by the AVS driver - Lots of DT schema conversions - Machine support for many AMD and Intel x86 platforms - Support for AMD ACP 7.1, Mediatek MT6367 and MT8365, Realtek RTL1320 SoundWire and rev C, and Texas Instruments TAS2563 USB-audio: - Add support of multiple control interfaces - A large rewrite of quirk table with macros - Support for RME Digiface USB HD-audio: - Cleanup of quirk code for Samsung Galaxy laptops - Clean up of detection of Cirrus codecs - C-Media CM9825 HD-audio codec support Others: - Rewrites to standard print API in a lot of legacy drivers" * tag 'sound-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (410 commits) ASoC: topology: Fix redundant logical jump ASoC: tas2781: Add Calibration Kcontrols for Chromebook ASoC: amd: acp: refactor SoundWire machine driver code ASoC: sdw_utils/intel: move soundwire endpoint parsing helper functions ASoC: sdw_util/intel: move soundwire endpoint and dai link structures ASoC: intel: sof_sdw: rename soundwire parsing helper functions ASoC: intel: sof_sdw: rename soundwire endpoint and dailink structures ASoC: atmel: mchp-pdmc: Retain Non-Runtime Controls ALSA: hda/realtek: Add support for Galaxy Book2 Pro (NP950XEE) ASoC: mediatek: mt7986-afe-pcm: Remove redundant error message ALSA: memalloc: Use proper DMA mapping API for x86 S/G buffer allocations ALSA: memalloc: Use proper DMA mapping API for x86 WC buffer allocations ALSA: usb-audio: Add logitech Audio profile quirk ASoc: mediatek: mt8365: Remove unneeded assignment ASoC: Intel: ARL: Add entry for HDMI-In capture support to non-I2S codec boards.
