Merge tag 'sound-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"There have been some significant changes in the core side, both for
ALSA and ASoC, while lots of development have been seen in SOF, as
well as many small fixes/improvements for ASoC codecs and platforms.
Below is a highlight in this cycle:
Core:
- The unification of PCM vmalloc buffer allocation helpers into the
standard API
- Clean up of the default PCM mmap handling for vmalloc & SG-buffer
- Fix potential races at ALSA timer open
- A few new PCM API extensions; just preliminary core changes, the
actual changes in drivers will be merged in 5.6
- Continued ASoC componentization works; now almost everything is a
common ASoC component object. A lot of refactoring and
simplification have been done along with it.
ASoC:
- Many fixes to the Sound Open Firmware (SOF) code
- Wake on voice support for Chromebooks
- SPI support and trigger word detection for RT5677
- New drivers for Analog Devices ADAU7118, Intel Cannonlake systems
with RT1011 and RT5682, Texas Instruments TAS2562 and TAS2770
HD-audio:
- Improved Intel DSP configuration / probe code for SOF
- Plumbing the legacy HD-audio driver with Intel SOF HDMI
- DP-MST support for Nvidia HDMI codecs
- Realtek quirks cleanups and new additions as usual
Others:
- Lots of refactoring and cleanups for FireWire; period-size sharing,
h/w IRQ interval configuration, clock recovery improvements, etc
- USB-audio: Scarlett mixer quirks
- Cleanups of PCM calls in various drivers (including media and USB)
to adapt the core API changes"
