[RFC,0/5] drm: rcar-du: Rework CRTC and groups for atomic commits

Message

Kieran Bingham March 15, 2019, 11:34 a.m. UTC

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.

Kieran Bingham (5):
  drm: rcar-du: Link CRTCs to the DU device
  drm: rcar-du: Provide for_each_group helper
  drm: rcar-du: Create a group state object
  drm: rcar-du: add group hooks for atomic-commit
  drm: rcar-du: Add crtc standby helpers
