[alsa-devel] [PATCH v2 0/8] Add support for voice control on Arizona ADSP

[Charles Keepax]

This series add support for voice control on wm8280/5110. This is
done by opening a compressed record channel, upon which data will
be available once the voice control functionality has been
triggered on the DSP.

Changes since v1:
 - Merged selecting of SND_SOC_COMPRESS into patch adding basic
   hookup as suggested by Vinod.
 - Fixed a minor typo in usleep_delay, which was using a longer
   delay than required.
 - Use kcalloc to allocate an array rather than caculating size
   manually.

Thanks,
Charles
