This patch series add a v4l2 m2m drvier for rockchip RGA direct rendering based
2d graphics acceleration module.
change in V2:
- generalize the controls.
- map buffers (10-50 us) in every cmd-run rather than in buffer-import to avoid
get_free_pages failed on
actively used systems.
- remove statu
Rockchip RGA is a separate 2D raster graphic acceleration unit. It
accelerates 2D graphics operations, such as point/line drawing, image
scaling, rotation, BitBLT, alpha blending and image blur/sharpness.
The drvier is mostly based on s5p-g2d v4l2 m2m driver.
And supports various operations from t

At peresent, we don't have a control for Compositing and Blend.
All drivers are just doing copies while actually many hardwares
supports more functions.
So Adding V4L2 controls for Compositing and Blend, used for for
composting streams.
The values are based on porter duff operations.
