Switch plane handling to use the atomic plane helpers. This means that
rather than provide our own implementations of .update_plane() and
.disable_plane(), we expose the lower-level check/prepare/commit/cleanup
entrypoints and let the DRM core implement update/disable for us using
those entrypoints.
The other main change that falls out of this patch is that our
drm_plane's will now always have a valid plane->state that contains the
relevant plane state (initial state is allocated at plane creation).
The base drm_plane_state pointed to holds the requested source/dest
coordinates, and the subclassed intel_plane_state holds the adjusted
values that our driver actually uses.
v2:
- Renamed file from intel_atomic.c to intel_atomic_plane.c (Daniel)
- Fix a copy/paste comment mistake (Bob)
v3:
- Use prepare/cleanup functions that we've already factored out
- Use newly refactored pre_commit/commit/post_commit to avoid sleeping
during vblank evasion
v4:
- Rebase to latest di-nightly requires adding an 'old_state' parameter
to atomic_update;
v5:
- Must have botched a rebase somewhere and lost some work. Restore
state 'dirty' flag to let begin/end code know which planes to
run the pre_commit/post_commit hooks for. This would have actually
shown up as broken in the next commit rather than this one.
v6:
- Squash kerneldoc patch into this one.
- Previous patches have now already taken care of most of the
infrastructure that used to be in this patch. All we're adding here
now is some thin wrappers.
v7:
- Check return of intel_plane_duplicate_state() for allocation
failures.
v8:
- Drop unused drm_plane_state -> intel_plane_state cast. (Ander)
- Squash in actual transition to plane helpers. Significant
refactoring earlier in the patchset has made the combined
prep+transition much easier to swallow than it was in earlier
iterations. (Ander)
