ASoC: cs35l56: Support for restoring calibration on
Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>:
These two patches add ALSA controls to support restoring factory calibration
during OS boot on ChromeOS.
ChromeOS applies calibration during boot using a process that has restricted
access permissions. This process needs ALSA controls for all settings that
it must restore.
