+Subject: [PATCH 0835/2940] drm/amd/dm: Understand why attaching path/tile
+ properties 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 configurations. Not sure what else there is to figure out.
