Merge tag 'sound-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "There are a few intensive changes in ALSA core side at this time that helped with significant code reduction. Meanwhile we keep getting new stuff, so the total size still grows... Anyway, the below are some highlights in this development cycle. ALSA core: - New helpers to manage page allocations and card object with devres - Refactoring for memory allocation with wc-pages - A new PCM hardware flag SNDRV_PCM_INFO_EXPLICIT_SYNC for controlling the explicit sync of the stream control; it'll be used for ASoC SOF and non-coherent memory in future ASoC: - Lots of cleanups and improvements to the Intel drivers, including some new systems support - New support for AMD Vangoh, CUI CMM-4030D-261, Mediatek Mt8195, Renesas RZ/G2L Mediatek Mt8195, RealTek RT101P, Renesas RZ/G2L, Rockchip RK3568 S/PDIF USB-audio: - Re-organized the quirk handling and a new option quirk_flags - Fix for a regression in 5.14 code change for JACK - Quirks for Sony WALKMAN, Digidesign mbox HD-audio: - Enhanced support for CS8409 codec - More consistent shutdown behavior with the runtime PM - The model option can accept the PCI or codec SSID as an alias - Quirks for ASUS ROG, HP Spectre x360 Others: - Lots of code reduction in legacy drivers with devres helpers - FireWire MOTU 896HD support" * tag 'sound-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (421 commits) ASoC: Revert PCM trigger changes ALSA: usb-audio: Add lowlatency module option ALSA: hda/cs8409: Initialize Codec only in init fixup. ALSA: hda/cs8409: Ensure Type Detection is only run on startup when necessary ALSA: usb-audio: Work around for XRUN with low latency playback ALSA: pcm: fix divide error in snd_pcm_lib_ioctl ASoC: soc-pcm: test refcount before triggering ASoC: soc-pcm: protect BE dailink state changes in trigger ASoC: wcd9335: Disable irq on slave ports in the remove function ASoC: wcd9335: Fix a memory leak in the error handling path of the probe function ASoC: wcd9335: Fix a double irq free in the remove function ALSA: hda: Disable runtime resume at shutdown ASoC: rockchip: i2s: Add support for frame inversion ASoC: dt-bindings: rockchip: Add compatible strings for more SoCs ASoC: rockchip: i2s: Add compatible for more SoCs ASoC: rockchip: i2s: Make playback/capture optional ASoC: rockchip: i2s: Fixup config for DAIFMT_DSP_A/B ASoC: dt-bindings: rockchip: Document reset property for i2s ASoC: rockchip: i2s: Fix regmap_ops hang ASoC: rockchip: i2s: Improve dma data transfer efficiency ...
