 - rockchip,grf: this soc should set GRF regs to mux vopl/vopb.
 - ports: contain a port node with endpoint definitions as defined in [2].
   For vopb,set the reg = <0> and set the reg = <1> for vopl.
+- video port 0 for the VOP input, the remote endpoint maybe vopb or vopl
+- video port 1 for either a panel or subsequent encoder
 
 Optional properties:
 - power-domains: a phandle to mipi dsi power domain node.
