[PATCH 08/20] drm/amd/display: Add DIGD case when getting retimer settings

[Harry Wentland]

From: Andrew Jiang <Andrew.Jiang at amd.com>

One of the HDMI ports map to DIGD, which we did not map to DP3 ext
HDMI settings. Add the DIGD case so that we can get proper retimer
settings from SBIOS for that port.
