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
