An early iteration for refactoring the RCAR-DU so that the group and CRTC state is only changed during rcar_du_atomic_commit_tail. Currnently, various parts of the group and crtc are adjusted and state is stored globaly. Introduce a private object state for the groups so that we can track per-state group-state, and start to utilise that to refactor so that all hardware operations can occur during rcar_du_atomic_commit_tail(). This is only RFC state at the moment, and I am actively working on this code.
