Can you clarify if you are fixing an issue on TGL - which isn't 
supported in the mainline? Or fixing an issue with SKL w/ HDaudio support?

FWIW, I couldn't make HDaudio codec support work on KBL, with the 
changes in ASoC core, the HDaudio support is broken with the SKL driver 
(or depends on an unreleased topology). See traces at:
