From: Diego Santa Cruz <Diego.SantaCruz@xxxxxxxxxxxx> commit 919bef7a106ade2bda73681bbc2f3678198f44fc upstream. The quirk added in upstream commit 90c3e2198777 ("drm/i915/glk: Add Quirk for GLK NUC HDMI port issues.") is also required on the ECS Liva Q2. Note: Would be nicer to figure out the extra delay required for the retimer without quirks, however don't know how to check for that.
