I am personally interested for tests but I doubt this option is usable 
by anyone outside of Intel - additional issues with probe race 
conditions with i915, e.g. on Linus' Dell XPS 9350, no DMIC support and 
not selected anyways by Jaroslav's new logic, no UCM, and no plans for 
the use of the HDMI common codec.

In case you didn't see it, the Skylake driver 'HDaudio codec' option is 
suggested as one of the 'unsupported' features here:
