[PATCH 3/5] ASoC: wm_adsp: Add support for SYSTEM firmware controls

From: Richard Fitzgerald
Date: Wed Nov 09 2016 - 12:15:18 EST


From: Stuart Henderson <stuarth@xxxxxxxxxxxxxxxxxxxxxxxxxxx>

Add support for firmware controls marked SYSTEM. These are
internal to the driver-firmware interface and do not have
a user-accessible ALSA control.
