Merge tag 'sound-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "The most significant changes at this cycle are the Sound Open Firmware support from Intel for the common DSP framework along with its support for Intel platforms. It's a door opened to a real "free" firmware (in the sense of FOSS), and other parties show interests in it. In addition to SOF, we've got a bunch of updates and fixes as usual. Some highlights are below. ALSA core: - Cleanups and fixes in ALSA timer code to cover some races spotted by syzkaller - Cleanups and fixes in ALSA sequencer code to cover some races, again unsurprisingly, spotted by syzkaller - Optimize the common page allocation helper with alloc_pages_exact() ASoC: - Add SOF core support, as well as Intel SOF platform support - Generic card driver improvements: support for MCLK/sample rate ratio and pin switches - A big set of improvements to TLV320AIC32x4 drivers - New drivers for Freescale audio mixers, several Intel machines, several Mediatek machines, Meson G12A, Spreadtrum compressed audio and DMA devices HD-audio: - A few Realtek codec fixes for reducing pop noises - Quirks for Chromebooks - Workaround for faulty connection report on AMD/Nvidia HDMI Others: - A quirk for Focusrite Scarlett Solo USB-audio - Add support for MOTU 8pre FireWire - 24bit sample format support in aloop - GUS patch format support (finally, over a decade) in native emux synth code" * tag 'sound-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (375 commits) ASoC: SOF: Fix unused variable warnings ALSA: line6: toneport: Fix broken usage of timer for delayed execution ALSA: aica: Fix a long-time build breakage ALSA: hda/realtek - Support low power consumption for ALC256 ASoC: stm32: i2s: update pcm hardware constraints ASoC: codec: hdac_hdmi: no checking monitor in hw_params ASoC: mediatek: mt6358: save PGA for mixer control ASoC: mediatek: mt6358: save output volume for mixer controls ASoC: mediatek: mt6358: initialize setting when ramping volume ASoC: SOF: core: fix undefined nocodec reference ASoC: SOF: xtensa: fix undefined references ASoC: SOF: Propagate sof_get_ctrl_copy_params() error properly ALSA: hdea/realtek - Headset fixup for System76 Gazelle (gaze14) ALSA: hda/intel: add CometLake PCI IDs ALSA: hda/realtek - Support low power consumption for ALC295 ASoC: rockchip: Fix an uninitialized variable compile warning ASoC: SOF: Fix a compile warning with CONFIG_PCI=n ASoC: da7219: Fix a compile warning at CONFIG_COMMON_CLK=n ASoC: sound/soc/sof/: fix kconfig dependency warning ASoC: stm32: spdifrx: change trace level on iec control ...
