Tianma Micro-electronics TM070RVHG71 7.0" WXGA TFT LCD panel



Required properties:

- compatible: should be "tianma,tm070rvhg71"

- power-supply: single regulator to provide the supply voltage

- backlight: phandle of the backlight device attached to the panel



Required nodes:

- port: LVDS port mapping to connect this display



This panel needs single power supply voltage. Its backlight is conntrolled

via PWM signal.



Example:

--------



Example device-tree definition when connected to iMX6Q based board



	panel: panel-lvds0 {

		compatible = "tianma,tm070rvhg71";

		backlight = <&backlight_lvds>;

		power-supply = <&reg_lvds>;



		port {

			panel_in_lvds0: endpoint {

				remote-endpoint = <&lvds0_out>;

			};

		};

	};
