I guess we could allow bridges to chain up and have multiple
child-bridges or something like that. Plus a helper which finds a
suitable routing through this network (it should be a tree after all,
so no ambiguity) given a drm_connector/drm_encoder pair. Or maybe I
misunderstand what you mean by going from 1 bridge to multiple bridges
