Jacob Chen f7e7b48e6d [media] rockchip/rga: v4l2 m2m support
Rockchip RGA is a separate 2D raster graphic acceleration unit. It

scaling, rotation, BitBLT, alpha blending and image blur/sharpness

The driver supports various operations from the rendering pipeline.
 - copy
 - fast solid color fill
 - rotation
 - flip

The code in rga-hw.c is used to configure regs according to operations
The code in rga-buf.c is used to create private mmu table for RGA.
