[PATCH v2 0/5] Implement komeda DRM-Plane

[james qian wang (Arm Technology China)]

This is the 3rd patchset for the komeda driver.

This patchset implemented plane/plane_helper functions for DRM-Plane.
per the komeda driver design, A DRM-plane maps to komeda layer input
pipeline, so the plane->atomic_check will build a layer input pipeline
according to the plane_state. and with this build function the plane_state
will be covert to komeda private component states to represent the real
HW configuration.

Beside that also added some basic functions for operating the komeda
private object.

v2:
- Rebase
- Introduce struct komeda_data_flow_cfg
- Update code after applied commit:
  b962a12050a3 ("drm/atomic: integrate modeset lock with private objects")

james qian wang (Arm Technology China) (5):
  drm: Add drm_atomic_get_old/new_private_obj_state
  drm/komeda: Add komeda_pipeline/component_get_state_and_set_user
  drm/komeda: Initialize komeda component as drm private object
  drm/komeda: Add komeda_build_layer_data_flow
  drm/komeda: Add komeda_plane/plane_helper_funcs
