    drm: add tile_group support. (v3) · 138f9ebb
    Dave Airlie authored
    A tile group is an identifier shared by a single monitor,
    DisplayID topology has 8 bytes we can use for this, just
    use those for now until something else comes up in the
    future. We assign these to an idr and use the idr to
    tell userspace what connectors are in the same tile group.
    
    DisplayID v1.3 says the serial number must be unique for
    displays from the same manufacturer.
    
    v2:
    destroy idr (dvdhrm)
    add docbook (danvet)
    airlied:- not sure how to make docbook add fns to tile group section.
    
    v3: fix missing unlock.
