Merge tag 'sound-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "At this time, it's an interesting mixture of changes for both old and new stuff. Majority of changes are about ASoC (lots of systematic changes for converting remove callbacks to void, and cleanups), while we got the fixes and the enhancements of very old PCI cards, too. Here are some highlights: ALSA/ASoC Core: - Continued effort of more ASoC core cleanups - Minor improvements for XRUN handling in indirect PCM helpers - Code refactoring of PCM core code ASoC: - Continued feature and simplification work on SOF, including addition of a no-DSP mode for bringup, HDA MLink and extensions to the IPC4 protocol - Hibernation support for CS35L45 - More DT binding conversions - Support for Cirrus Logic CS35L56, Freescale QMC, Maxim MAX98363, nVidia systems with MAX9809x and RT5631, Realtek RT712, Renesas R-Car Gen4, Rockchip RK3588 and TI TAS5733 ALSA: - Lots of works for legacy emu10k1 and ymfpci PCI drivers - PCM kselftest fixes and enhancements" * tag 'sound-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (586 commits) ALSA: emu10k1: use high-level I/O in set_filterQ() ALSA: emu10k1: use high-level I/O functions also during init ALSA: emu10k1: fix error handling in snd_audigy_i2c_volume_put() ALSA: emu10k1: don't stop DSP in _snd_emu10k1_{,audigy_}init_efx() ALSA: emu10k1: fix SNDRV_EMU10K1_IOCTL_SINGLE_STEP ALSA: emu10k1: skip Sound Blaster-specific hacks for E-MU cards ALSA: emu10k1: fixup DSP defines ALSA: emu10k1: pull in some register definitions from kX-project ALSA: emu10k1: remove some bogus defines ALSA: emu10k1: eliminate some unused defines ALSA: emu10k1: fix lineup of EMU_HANA_* defines ALSA: emu10k1: comment updates ALSA: emu10k1: fix snd_emu1010_fpga_read() input masking for rev2 cards ALSA: emu10k1: remove unused emu->pcm_playback_efx_substream field ALSA: emu10k1: remove unused `resume` parameter from snd_emu10k1_init() ALSA: emu10k1: minor optimizations ALSA: emu10k1: remove remaining cruft from snd_emu10k1_emu1010_init() ALSA: emu10k1: remove apparently pointless EMU_HANA_OPTION_CARDS reads ALSA: emu10k1: remove apparently pointless FPGA reads ALSA: emu10k1: stop doing weird things with HCFG in snd_emu10k1_emu1010_init() ...
