Merge tag 'sound-5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "Lots of code development have been see in ASoC side as usual, while the continued development on memalloc helper and USB-audio low- latency support are found in the rest. Note that a few changes in the unusual places like arch/sh are included, which are a part of ASoC DAI format cleanups. ALSA core: - Continued memalloc helper updates and cleanups, now supporting non-coherent and non-contiguous pages - Fixes for races in mixer OSS layer ASoC: - A new version of the audio graph card which supports a wider range of systems - Several conversions to YAML DT bindings - Continuing cleanups to the SOF and Intel code - Move of the Cirrus DSP framework into drivers/firmware to allow for future use by non-audio DSPs - An overhaul of the cs42l42 driver, correcting many problems - DAI format terminology conversions over many drivers for cleanups - Support for AMD Vangogh and Yelow Cap, Cirrus CS35L41, Maxim MAX98520 and MAX98360A, Mediatek MT8195, Nuvoton NAU8821, nVidia Tegra210, NXP i.MX8ULP, Qualcomm AudioReach, Realtek ALC5682I-VS, RT5682S, and RT9120 and Rockchip RV1126 and RK3568 USB-audio: - Continued improvements on low-latency playback - Quirks for Pioneer devices, Line6 HX-Stomp XL, Audient iD14 HD-audio: - Reduce excessive udelay() calls on Intel platforms; this should reduce the CPU load with PulseAudio - Quirks for HP and Clevo laptops FireWire: - Support for meter information on MOTU" * tag 'sound-5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (513 commits) ALSA: usb-audio: Add quirk for Audient iD14 ALSA: hda/realtek: Add quirk for Clevo PC70HS ALSA: usb-audio: Line6 HX-Stomp XL USB_ID for 48k-fixed quirk ALSA: usb-audio: Add registration quirk for JBL Quantum 400 ASoC: rsnd: Fix an error handling path in 'rsnd_node_count()' ASoC: tlv320aic3x: Make aic3x_remove() return void ASoC: Intel: soc-acpi: use const for all uses of snd_soc_acpi_codecs ASoC: Intel: soc-acpi-cht: shrink tables using compatible IDs ASoC: Intel: soc-acpi-byt: shrink tables using compatible IDs ASoC: Intel: sof_rt5682: use comp_ids to enumerate rt5682s ASoC: Intel: sof_rt5682: detect codec variant in probe function ASoC: soc-acpi: add comp_ids field for machine driver matching ASoC: mediatek: mt8195: add mt8195-mt6359-rt1011-rt5682 bindings document ASoC: mediatek: mt8195: add machine driver with mt6359, rt1011 and rt5682 ASoC: Stop dummy from overriding hwparams ASoC: topology: Change topology device to card device ASoC: topology: Use correct device for prints ASoC: topology: Check for dapm widget completeness ASoC: topology: Add header payload_size verification ASoC: core: Remove invalid snd_soc_component_set_jack call ...
