[media] rockchip/rga: v4l2 m2m support
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 driver supports various operations from the rendering pipeline.
- copy
- fast solid color fill
- rotation
- flip
- alpha blending
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.
