--- Comment #13 from Manasi <manasi.d.navare at intel.com> ---
You cannot absolutely revert the "drm/i915/edp: Do not do link training
fallback or prune modes on EDP" this patch since now with reverting this, it is
falling back to lower value and pruning out the only native mode on the panel.

I think clearly this is a panel where we need to follow a sequence of retrying
the CR after 5 failures on Channel EQ. To test this we will need to revert all
the patches that fix the CR and Channel EQ sequencing for compliance.

Let me also meanwhile try to create a patch that retries CR after Channel EQ
failure.
