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"
