Merge tag 'sound-4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"Here is the update of sound bits for 4.11: again at this time, no big
changes in ALSA and ASoC core but only cosmetic changes like
consitifaction.
Meanwhile, quite a lot of developments are seen in a few driver side.
ALSA Core:
- Clean up, consitification of some ops
HD-audio:
- A slight behavior change of single_cmd option
- Quirks for AmigaOne X1000, Samsung Ativ Book 8, Dell AiO, ALC221
HP, and fixes for Lewisburg controller
- Realtek ALC299, ALC1220 codecs
Others:
- USB-audio: Tascam US-16x08 DSP mixer quirk
- Intel HDMI LPE audio support for Baytrail / Cherrytrail; this
contains some updates in drm/i915 for the new platform binding
ASoC:
- Lots of updates in Intel drivers, mostly for DisplayPort and HDMI
on Skylake and onwards, as well as more Baytrail / Cherrytrail
boards support
- Channel mapping support for HDMI
- Support for AllWinner A31 and A33, Everest Semiconductor ES8328,
Nuvoton NAU8540.
