Sharp 15" LQ150X1LG11 XGA TFT LCD panel



Required properties:

- compatible: should be "sharp,lq150x1lg11"

- power-supply: regulator to provide the VCC supply voltage (3.3 volts)



Optional properties:

- backlight: phandle of the backlight device

- rlud-gpios: a single GPIO for the RL/UD (rotate 180 degrees) pin.

- sellvds-gpios: a single GPIO for the SELLVDS pin.



If rlud-gpios and/or sellvds-gpios are not specified, the RL/UD and/or SELLVDS

pins are assumed to be handled appropriately by the hardware.



Example:



	backlight: backlight {

		compatible = "pwm-backlight";

		pwms = <&pwm 0 100000>;                      /* VBR */



		brightness-levels = <0 20 40 60 80 100>;

		default-brightness-level = <2>;



		power-supply = <&vdd_12v_reg>;               /* VDD */

		enable-gpios = <&gpio 42 GPIO_ACTIVE_HIGH>;  /* XSTABY */

	};



	panel {

		compatible = "sharp,lq150x1lg11";



		power-supply = <&vcc_3v3_reg>;               /* VCC */



		backlight = <&backlight>;

		rlud-gpios = <&gpio 17 GPIO_ACTIVE_HIGH>;    /* RL/UD */

		sellvds-gpios = <&gpio 18 GPIO_ACTIVE_HIGH>; /* SELLVDS */

	};
