Merge tag 'sound-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "The amount of changes is smaller at this round (what a surprise), but lots of activity is seen. Most of changes are about ASoC driver development, especially Intel platforms. Here are some highlights: General: - Replace all tasklet usages with other alternatives - Cleanup of the ASoC error unwinding code - Fixes for trivial issues caught by static checker - Spell fixes allover the places ALSA Core: - Lockdep fix for control devices - Fix for potential OSS sequencer mutex stalls HD-audio and USB-audio: - SoundBlaster AE-7 support - Changes in quirk table for the rename handling - Quirks for HP and ASUS machines, Pioneer DJ DJM-250MK2. ASoC: - Lots of updates for Intel SOF and SoundWire enablement - Replacement of the DSP driver for some older x86 systems; the new code was written from scratch, better maintenance expected - Helpers for parsing auxiluary devices from the device tree - New support for AllWinner A64, Cirrus Logic CS4234, Mediatek MT6359 Microchip S/PDIF TX and RX controllers, Realtek RT1015P, and Texas Instruments J721E, TAS2110, TAS2564 and TAS2764" * tag 'sound-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (498 commits) ALSA: hda/hdmi: fix incorrect locking in hdmi_pcm_close ALSA: hda: fix jack detection with Realtek codecs when in D3 ALSA: fireworks: use semicolons rather than commas to separate statements ALSA: hda: use semicolons rather than commas to separate statements ALSA: hda/i915 - fix list corruption with concurrent probes ASoC: dmaengine: Document support for TX only or RX only streams ASoC: mchp-spdiftx: remove 'TX' from playback stream name ASoC: ti: davinci-mcasp: Use &pdev->dev for early dev_warn ASoC: tas2764: Add the driver for the TAS2764 dt-bindings: tas2764: Add the TAS2764 binding doc ASoC: Intel: catpt: Add explicit DMADEVICES kconfig dependency ASoC: Intel: catpt: Fix compilation when CONFIG_MODULES is disabled ASoC: stm32: dfsdm: add actual resolution trace ASoC: stm32: dfsdm: change rate limits ASoC: qcom: sc7180: Add support for audio over DP Asoc: qcom: lpass-platform : Increase buffer size ASoC: qcom: Add support for lpass hdmi driver Asoc: qcom: lpass:Update lpaif_dmactl members order Asoc:qcom:lpass-cpu:Update dts property read API ASoC: dt-bindings: Add dt binding for lpass hdmi ...
