Subject: [PATCH] drm/i915/glk: ECS Liva Q2 needs GLK HDMI port timing quirk
Date: Thu, 16 Jun 2022 15:41:37 +0300	[thread overview]
Message-ID: <20220616124137.3184371-1-jani.nikula@intel.com> (raw)

From: Diego Santa Cruz <Diego.SantaCruz@spinetix.com>

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.

Cc: stable@vger.kernel.org
Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/1326
