Merge tag 'sound-4.21-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "There are no intensive changes in both ALSA and ASoC core parts while rather most of changes are a bunch of driver fixes and updates. A large diff pattern appears in ASoC TI part which now merges both OMAP and DaVinci stuff, but the rest spreads allover the places. Note that this pull request includes also some updates for LED trigger and platform drivers for mute LEDs, appearing in the diffstat as well. Some highlights: ASoC: - Preparatory work for merging the audio-graph and audio-graph-scu cards - A merge of TI OMAP and DaVinci directories, as both product lines get merged together. Also including a few architecture changes as well. - Major cleanups of the Maxim MAX9867 driver - Small fixes for tablets & co with Intel BYT/CHT chips - Lots of rsnd updates as usual - Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S controllers HD-audio: - Introduce audio-mute LED trigger for replacing the former hackish dynamic binding - Huawei WMI hotkey and mute LED support - Refactoring of PM code and display power controls - Headset button support in the generic jack code - A few updates for Tegra - Fixups for HP EliteBook and ASUS UX391UA - Lots of updates for Intel ASoC HD-audio, including the improved DSP detection and the fallback binding from ASoC SST to legacy HD-audio controller drivers Others: - Updates for FireWire TASCAM and Fireface devices, some other fixes - A few potential Spectre v1 fixes that are all trivial" * tag 'sound-4.21-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (280 commits) ALSA: HD-Audio: SKL+: force HDaudio legacy or SKL+ driver selection ALSA: HD-Audio: SKL+: abort probe if DSP is present and Skylake driver selected ALSA: HDA: export process_unsol_events() ALSA: hda/realtek: Enable audio jacks of ASUS UX391UA with ALC294 ALSA: bebob: fix model-id of unit for Apogee Ensemble ALSA: emu10k1: Fix potential Spectre v1 vulnerabilities ALSA: rme9652: Fix potential Spectre v1 vulnerability ASoC: ti: Kconfig: Remove the deprecated options ARM: davinci_all_defconfig: Update the audio options ARM: omap1_defconfig: Do not select ASoC by default ARM: omap2plus_defconfig: Update the audio options ARM: davinci: dm365-evm: Update for the new ASoC Kcofnig options ARM: OMAP2: Update for new MCBSP Kconfig option ARM: OMAP1: Makefile: Update for new MCBSP Kconfig option MAINTAINERS: Add entry for sound/soc/ti and update the OMAP audio support ASoC: ti: Merge davinci and omap directories ALSA: hda: add mute LED support for HP EliteBook 840 G4 ALSA: fireface: code refactoring to handle model-specific registers ALSA: fireface: add support for packet streaming on Fireface 800 ALSA: fireface: allocate isochronous resources in mode-specific implementation ...
