Merge tag 'sound-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "As the diffstat shows, we've had lots of developments in a wide range at this time; the majority of changes are about ASoC, including subsystem-wide cleanups, continued SOF / Intel updates and a bunch of new drivers (as usual), while there have been some significant (but almost invisible) improvements in ALSA core side, too. Below are some highlights: Core: - Faster lookups of control elements with Xarray; normal user won't notice, but on the devices with tons of control elements, it can be visibly faster - Support for input validation for controls; this will harden for badly written drivers in general with a slight overhead - Deferred async signal handling for working around the potential deadlocks - Cleanup / refactoring raw MIDI locking code ASoC: - Restructing of the set_fmt() callbacks for making things clearer in situations like CODEC to CODEC links - Clean up and modernizing the DAI naming scheme setups - Merge of more of the Intel AVS driver stack, including some board integrations - New version 4 mechanism for communication with SOF DSPs - Suppoort for dynamically selecting the PLL to use at runtime on i.MX platforms - Improvements for CODEC to CODEC support in the generic cards - Support for AMD Jadeite and various machines, AMD RPL, Intel MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and WAS883x, and Texas Instruments TAS2780 HD- and USB-audio: - Continued improvement for CS35L41 (sub)codec support - More quirks for various devices (HP, Lenovo, Dell, Clevo)" * tag 'sound-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (778 commits) ALSA: hda/realtek: Add quirk for HP Spectre x360 15-eb0xxx ALSA: line6: Replace sprintf() with sysfs_emit() ALSA: hda: Replace sprintf() with sysfs_emit() ALSA: pcm: Replace sprintf() with sysfs_emit() ALSA: core: Replace scnprintf() with sysfs_emit() ALSA: control-led: Replace sprintf() with sysfs_emit() ALSA: aoa: Replace sprintf() with sysfs_emit() ALSA: ac97: Replace sprintf() with sysfs_emit() ALSA: hda/realtek: Add quirk for Clevo NV45PZ ALSA: hda/realtek: Add quirk for Lenovo Yoga9 14IAP7 ALSA: control: Use deferred fasync helper ALSA: pcm: Use deferred fasync helper ALSA: timer: Use deferred fasync helper ALSA: core: Add async signal helpers ASoC: q6asm: use kcalloc() instead of kzalloc() ACPI: scan: Add CLSA0101 Laptop Support ALSA: hda: cs35l41: Support CLSA0101 ALSA: hda: cs35l41: Use the CS35L41 HDA internal define ASoC: dt-bindings: use spi-peripheral-props.yaml ASoC: codecs: va-macro: use fsgen as clock ...
