Subject: [PATCH] drm/amd/dm: Understand why attaching path/tile properties are needed
Git-commit: 04ac4b0ed412f65230b456fcd9aa07e13befff89
Patch-mainline: v4.20-rc5
References: bsc#1111666

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.
