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"
