--- Comment #20 from Manasi <manasi.d.navare at intel.com> ---
Retrying the Clock recovery phase 5 times without giving up is what the hack
used to do earlier before it was removed for DP compliance passing.
But looks like there are more non compliant panels than the compliant ones and
may be we need that hack permanently so that the driver doesnt fallback the
link parameters way too quickly.
This same work around probably could be tried for :
