So this patch just properly documents them. Note that pointing directly at the attachment might have issues for devices that have multiple struct device *dev parts constituting the logical gpu and so might need multiple attachment points. Similarly for drm devices which don't need a dma attachment at all (like udl). But fixing that up is material for different patches.
