7*b1f487efSJohan Jonkertitle: Rockchip 2D raster graphic acceleration controller (RGA)
8*b1f487efSJohan Jonker
9*b1f487efSJohan Jonkerdescription:
10*b1f487efSJohan Jonker  RGA is a standalone 2D raster graphic acceleration unit. It accelerates 2D
11*b1f487efSJohan Jonker  graphics operations, such as point/line drawing, image scaling, rotation,
12*b1f487efSJohan Jonker  BitBLT, alpha blending and image blur/sharpness.
