Subject: [PATCH v3 26/41] drm: renesas: shmobile: Unify plane allocation
Unify primary and overlay plane allocation:
- Enhance shmob_drm_plane_create() so it can be used to create the
primary plane, too,
- Move overlay plane creation next to primary plane creation.
Signed-off-by: Geert Uytterhoeven <geert+renesas@...der.be>
---
v3:
- No changes,
v2:
- Pass plane type to shmob_drm_plane_create() to avoid having to shift
all overlay plane indices by one,
- Rename primary_plane_funcs to shmob_drm_primary_plane_funcs,
- Rename shmob_drm_plane_funcs to shmob_drm_overlay_plane_funcs.
