This Design enable Xilinx VPSS-SC (Scaler) to work as Mem 2 Mem Device. Xilinx Frame buffer Read → Xilinx VPSS-CSC → Xilinx VPSS-Scaler → Xilinx Frame buffer write act as composite device.

This reference design is with ZCU102
Device tree binding
The dts node should be defined with correct configuration. The common dts properties are described in video.txt
