Subject: [Intel-gfx] [PATCH v2 14/18] drm/i915: Handle downstream facing ports w/o EDID
Date: Fri,  4 Sep 2020 14:53:50 +0300	[thread overview]
Message-ID: <20200904115354.25336-15-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20200904115354.25336-1-ville.syrjala@linux.intel.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Use drm_dp_downstream_mode() to get a suitable mode for downstream
facing ports which don't have an EDID.
