Subject: [PATCH v7 12/17] drm: rcar-du: Move rcar_du_vsp_plane_atomic_update()
Move rcar_du_vsp_plane_atomic_update() to RCar DU vsp lib so that
both RCar and RZ/G2L DU vsp drivers can share this function.
Signed-off-by: Biju Das <biju.das.jz@...renesas.com>
---
v6->v7:
* Rebased to drm-tip.
v1->v6:
* Rebased on drm-misc-next and DU-next.
v1:
* Created the lib suggested by Laurent.
