Merge tag 'sound-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"The majority of this update is about ASoC, including a few new
drivers, and the rest are mostly minor changes. The only substantial
change in ALSA core is about the additional error handling in the
compress-offload API. Below are highlights:
- Add the error propagating support in compress-offload API
- HD-audio: a usual Dell headset fixup, an Intel HDMI/DP fix, and the
default mixer setup change ot turn off the loopback
- Lots of updates for ASoC Intel drivers, mostly board support and
bug fixing, and to the NAU8825 driver
- Work on generalizing bits of simple-card to allow more code sharing
with the Renesas rsrc-card (which can't use simple-card due to DPCM)
- Removal of the Odroid X2 driver due to replacement with simple-card
- Support for several new Mediatek platforms and associated boards
- New ASoC drivers for Allwinner A10, Analog Devices ADAU7002,
Broadcom Cygnus, Cirrus Logic CS35L33 and CS53L30, Maxim MAX8960
and MAX98504, Realtek RT5514 and Wolfson WM8758"
