+ This is a v4l2 driver for Rockchip SOC RGA 2d graphics accelerator.
+ 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.
+
+ To compile this driver as a module choose m here.
