    7 title: Rockchip 2D raster graphic acceleration controller (RGA)
    8 
    9 description:
   10   RGA is a standalone 2D raster graphic acceleration unit. It accelerates 2D
   11   graphics operations, such as point/line drawing, image scaling, rotation,
   12   BitBLT, alpha blending and image blur/sharpness.
