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")
