Message

The Google Chameleon v3 is a device made for testing audio and video
paths of other devices. This patchset adds support for ASoC audio on
this device. It has two audio sources: HDMI audio from the it68051 chip
(RX only), and analog audio from the ssm2603 chip (RX and TX).

The patchset adds the ASoC platform and codec drivers, as well as some
changes to the existing ssm2602 codec driver.

v2 changes:
  * Replace chv3-audio machine driver with simple-audio-card
  * Use regmap_register_patch() in ssm2602 workaround
  * Remove ssm2602 mute gpio patch, add a gpio hog instead
  * Simplify hw_pointer logic in chv3-i2s
  * Commit splits & other misc changes
