+-----------------------------------------------------
+Required properties:
+- compatible :
+ "atmel,sama5d2-hlcdc".
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- clocks: phandles to input clocks.
+- atmel,vl-bpix: Bits per pixel.
+- atmel,guard-time: lcd guard time (Delay in frame periods).
+- display-timings: please refer the displaymode.txt.

+ atmel,guard-time = <1>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_lcd_base &pinctrl_lcd_pwm &pinctrl_lcd_rgb666>;
+ status = "okay";
+
+ display-timings {
+ 480x272 {
+ clock-frequency = <9000000>;
+ hactive = <480>;
+ vactive = <272>;
