Thanks Shuming.

I will add my own

tag, but this driver was also tested by others at Intel, including Bard 
Liao and Rander Wang, on CometLake, IceLake and TigerLake platforms. I 
am not aware of any issues with this codec, and jack detection was 
tested extensively.

The key point to be reviewed is the use of regmap, where we disable 
access to the registers until the device becomes ATTACHED (cache-only), 
and also make sure hw calibration is rerun (cache-bypass) before 
restoring settings in the resume step.

This patch also depends on interface changes on the SoundWire side, see 
below what Vinod provided before the holiday break
