Pull sound updates from Takashi Iwai: "This became wide and scattered updates all over the sound tree as diffstat shows: lots of (still ongoing) refactoring works in ASoC, fixes and cleanups caught by static analysis, inclusive term conversions as well as lots of new drivers. Below are highlights: ASoC core: - API cleanups and conversions to the unified mute_stream() call - Simplify I/O helper functions - Use helper macros to retrieve RTD from substreams ASoC drivers: - Lots of fixes and cleanups in Intel ASoC drivers - Lots of new stuff: Freescale MQS and i.MX6sx, Intel KeemBay I2S, Maxim MAX98360A and MAX98373 SoundWire, various Mediatek boards, nVidia Tegra 186 and 210, RealTek RL6231, Samsung Midas and Aries boards, TI J721e EVM ALSA core: - Minor code refacotring for SG-buffer handling HD-audio: - Generalization of mute-LED handling with LED classdev - Intel silent stream support for HDMI - Device-specific fixes: CA0132, Loongson-3 Others: - Usual USB- and HD-audio quirks for various devices - Fixes for echoaudio DMA position handling - Various documents and trivial fixes for sparse warnings - Conversion to adopt inclusive terms" * tag 'sound-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (479 commits) ALSA: pci: delete repeated words in comments ALSA: isa: delete repeated words in comments ALSA: hda/tegra: Add 100us dma stop delay ALSA: hda: Add dma stop delay variable ASoC: hda/tegra: Set buffer alignment to 128 bytes ALSA: seq: oss: Serialize ioctls ALSA: hda/hdmi: Add quirk to force connectivity ALSA: usb-audio: add startech usb audio dock name ALSA: usb-audio: Add support for Lenovo ThinkStation P620 Revert "ALSA: hda: call runtime_allow() for all hda controllers" ALSA: hda/ca0132 - Fix AE-5 microphone selection commands.
