+Rockchip specific extensions to the Synopsys Designware MIPI DSI
+================================
+
+Required properties:
+- compatible: "rockchip,rk3288-mipi-dsi", "snps,dw-mipi-dsi".
+- rockchip,grf: this soc should set GRF regs to mux vopl/vopb.
+- ports: contain a port node with endpoint definitions as defined in [1].
+  For vopb,set the reg = <0> and set the reg = <1> for vopl.
+
+For more required properties, please refer to [2].
