Merge tag 'sound-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "This became again a busy development cycle. There are few ALSA core updates (merely API cleanups and sparse fixes), with the majority of other changes are found in ASoC scene. Here are some highlights: ALSA core: - More helper macros for sparse warning fixes (e.g. bitwise types) - Slight optimization of PCM OSS locks - Make common handling for PCM / compress buffers (for SOF) ASoC: - Lots of code refactoring and modernization for (still ongoing) componentization works - Conversion of SND_SOC_ALL_CODECS to use imply - Continued refactoring and fixing of the Intel SOF/SST support, including the initial (but still incomplete) SoundWire support - SoundWire and more advanced clocking support for Realtek RT5682 - Support for amlogic GX, Meson 8, Meson 8B and T9015 DAC, Broadcom DSL/PON, Ingenic JZ4760 and JZ4770, Realtek RL6231, and TI TAS2563 and TLV320ADCX140 HD-audio: - Optimizations in HDMI jack handling - A few new quirks and fixups for Realtek codecs USB-audio: - Delayed registration support - New quirks for Motu, Kingston, Presonus" * tag 'sound-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (415 commits) ALSA: usb-audio: Fix case when USB MIDI interface has more than one extra endpoint descriptor Revert "ALSA: uapi: Drop asound.h inclusion from asoc.h" ALSA: hda/realtek - Remove now-unnecessary XPS 13 headphone noise fixups ALSA: hda/realtek - Set principled PC Beep configuration for ALC256 ALSA: doc: Document PC Beep Hidden Register on Realtek ALC256 ALSA: hda/realtek - a fake key event is triggered by running shutup ALSA: hda: default enable CA0132 DSP support ASoC: amd: acp3x-pcm-dma: clean up two indentation issues ASoC: tlv320adcx140: Remove undocumented property ASoC: Intel: sof_sdw: Add Volteer support with RT5682 SNDW helper function ASoC: Intel: common: add match table for TGL RT5682 SoundWire driver ASoC: Intel: boards: add sof_sdw machine driver ASoC: Intel: soc-acpi: update topology and driver name for SoundWire platforms ASoC: rt5682: move DAI clock registry to I2S mode ASoC: pxa: magician: convert to use i2c_new_client_device() ASoC: SOF: Intel: hda-ctrl: add reset cycle before parsing capabilities Asoc: SOF: Intel: hda: check SoundWire wakeen interrupt in irq thread ASoC: SOF: Intel: hda: add WAKEEN interrupt support for SoundWire ASoC: SOF: Intel: hda: add parameter to control SoundWire clock stop quirks ASoC: SOF: Intel: hda: merge IPC, stream and SoundWire interrupt handlers ...
