Merge tag 'sound-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "This one became bigger than usual, not in the total size but rather containing lots of small changes all over the places. The majority of changes are about ASoC, especially SOF / Intel stuff, and we see an interesting work for ASoC DAPM graph visualization, while there are many other code cleanup and refactoring, too. Core: - A deadlock fix at device disconnection - A new tool dapm-graph for visualising the DAPM state ASoC: - Large updates throughout the Intel audio drivers - Fixes and clarifications for the DAPM documentation - Cleanups of accessors for driver data, module labelling, and for constification - Modernsation and cleanup work in the Mediatek drivers - Several fixes and features for the DaVinci I2S driver - New drivers for several AMD and Intel platforms, Nuvoton NAU8325, Rockchip RK3308 and Texas Instruments PCM6240 HD-audio: - Cleanup for CONFIG_PM dependencies - Cirrus HD-audio codec fixes and quirks Others: - Series of tree-wide fixes in Makefiles to use *-y - Additions of missing module descriptions - Scarlett2 USB mixer enhancements - A series of legacy emu10k1 fixes and improvements" * tag 'sound-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (603 commits) ALSA: hda/realtek: Drop doubly quirk entry for 103c:8a2e ALSA: hda/realtek - fixed headset Mic not show ASoC: SOF: amd: Fix build error with built-in config ALSA: scarlett2: Increase mixer range to +12dB ALSA: scarlett2: Add S/PDIF source selection controls ALSA: core: Remove superfluous CONFIG_PM ALSA: Fix deadlocks with kctl removals at disconnection ASoC: audio-graph-card2: call of_node_get() before of_get_next_child() ASoC: SOF: amd: Correct spaces in Makefile ASoC: rt715-sdca-sdw: Fix wrong complete waiting in rt715_dev_resume() ASoC: Intel: sof_sdw_rt_amp: use dai parameter ASoC: Intel: sof_sdw: add dai parameter to rtd_init callback ASoC: Intel: sof_sdw: use .controls/.widgets to add controls/widgets ASoC: Intel: sof_sdw: add controls and dapm widgets in codec_info ASoC: Intel: sof_sdw: use generic name for controls/widgets ASoC: Intel: sof_sdw_cs_amp: rename Speakers to Speaker ASoC: Intel: maxim-common: change max98373 data to static ASoC: Intel: sof_sdw: add max98373 dapm routes ASoC: Intel: sof_rt5682: use max_98373_dai_link function ASoC: Intel: sof_nau8825: use max_98373_dai_link function ...
