added.

-Ingenic JZ47xx LCD driver
-
-Required properties:
-- compatible: one of:
-  * ingenic,jz4740-lcd
-  * ingenic,jz4725b-lcd
-  * ingenic,jz4770-lcd
-- reg: LCD registers location and length
-- clocks: LCD pixclock and device clock specifiers.
-	   The device clock is only required on the JZ4740.
-- clock-names: "lcd_pclk" and "lcd"
-- interrupts: Specifies the interrupt line the LCD controller is connected to.

-Example:
-
-panel {
-	compatible = "sharp,ls020b1dd01d";
-
-	backlight = <&backlight>;
-	power-supply = <&vcc>;
-
-	port {
-		panel_input: endpoint {
-			remote-endpoint = <&panel_output>;
