--- Comment #6 from Abhay Kumar <abhay.kumar at intel.com> ---
CD Clock frequency is 79.2 MHz in failing case and is 316.8 MHz in passing
case. Minimum frequency required for Audio Codec to operate on GLK is 96 MHz.
Hence the failing case is expected to fail. This is statement from windows
driver team.

Basically for 1080p panel where cdclk is 79.2 it fails and for 4k panel where
cdclk is 316.8 it passes. Looks like we need to check design. Any thoughts?
