Merge tag 'sound-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "This was a relatively calm development cycle. Most of changes are rather small device-specific fixes and enhancements. The only significant changes in ALSA core are code refactoring with the recent cleanup infrastructure, which should bring no functionality changes. Some highlights below: Core: - Lots of cleanups in ALSA core code with automatic kfree cleanup and locking guard macros - New ALSA core kunit test ASoC: - SoundWire support for AMD ACP 6.3 systems - Support for reporting version information for AVS firmware - Support DSPless mode for Intel Soundwire systems - Support for configuring CS35L56 amplifiers using EFI calibration data - Log which component is being operated on as part of power management trace events. - Support for Microchip SAM9x7, NXP i.MX95 and Qualcomm WCD939x HD- and USB-audio: - More Cirrus HD-audio codec support - TAS2781 HD-audio codec fixes - Scarlett2 mixer fixes Others: - Enhancement of virtio driver for audio control supports - Cleanups of legacy PM code with new macros - Firewire sound updates" * tag 'sound-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (307 commits) ALSA: usb-audio: Stop parsing channels bits when all channels are found. ALSA: hda/tas2781: remove unnecessary runtime_pm calls ALSA: hda/realtek - ALC236 fix volume mute & mic mute LED on some HP models ALSA: aaci: Delete unused variable in aaci_do_suspend ALSA: scarlett2: Fix Scarlett 4th Gen input gain range again ALSA: scarlett2: Fix Scarlett 4th Gen input gain range ALSA: scarlett2: Fix Scarlett 4th Gen autogain status values ALSA: scarlett2: Fix Scarlett 4th Gen 4i4 low-voltage detection ALSA: hda/tas2781: restore power state after system_resume ALSA: hda/tas2781: do not call pm_runtime_force_* in system_resume/suspend ALSA: hda/tas2781: do not reset cur_* values in runtime_suspend ALSA: hda/tas2781: add lock to system_suspend ALSA: hda/tas2781: use dev_dbg in system_resume ALSA: hda/realtek: fix ALC285 issues on HP Envy x360 laptops platform/x86: serial-multi-instantiate: Add support for CS35L54 and CS35L57 ALSA: hda: cs35l56: Add support for CS35L54 and CS35L57 ASoC: cs35l56: Add support for CS35L54 and CS35L57 ASoC: Intel: catpt: Carefully use PCI bitwise constants ALSA: hda: hda_component: Include sound/hda_codec.h ALSA: hda: hda_component: Add missing #include guards ...
