[PATCH v3 0/3] Add overlay plane support for ZTE drm driver

[Shawn Guo]

From: Shawn Guo <shawn.guo at linaro.org>

Changes for v3:
 - Let zx_plane be accessible from zx_vou driver, and so we can easily
   access all the data encoded in zx_plane with a drm_plane pointer.
   Thus, function zx_overlay_find_vl_idx() can be saved completely.
 - Refine the existing zx_plane driver a bit to support disable graphic
   layer, and make the support of overlay plane a bit easier, by sharing
   VOU layer setup and teardown functions between graphic and video
   layers.

Changes for v2:
 - Use clipped coordinates for overlay position calculation

Shawn Guo (3):
  drm: zte: make zx_plane accessible from zx_vou driver
  drm: zte: add .atomic_disable hook to disable graphic layer
  drm: zte: add overlay plane support
