From: Ville Syrjälä <ville.syrj...@linux.intel.com> All the bits in the VBT child device type have some speciifc meaning, so looking for an exact match isn't always the right thing. On some VLVs for example the device type for eDP panels is 0x1806.
If we mask out the bits that could concievably change between different eDP panels, we are left with the set of bits that should still tell us if the port is eDP or not.
