Subject: [PATCH 2/2] drm/amd/dm: Understand why attaching path/tile propert=
ies are needed

Path property is used for userspace to know what MST connector goes to what=
 actual DRM DisplayPort connector, the tiling property is for tiling config=
urations. Not sure what else there is to figure out.
