Rockchip specific extensions to the Synopsys Designware MIPI DSI
================================
Required properties:
- #address-cells: Should be <1>.
- #size-cells: Should be <0>.
- compatible: "rockchip,rk3288-mipi-dsi", "snps,dw-mipi-dsi".
- reg: Represent the physical address range of the controller.
- interrupts: Represent the controller's interrupt to the CPU(s).
- clocks, clock-names: Phandles to the controller's pll reference
clock(ref) and APB clock(pclk), as described in [1].
- 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.
