TPO TPG110 Panel

================



This binding builds on the DPI bindings, adding a few properties

as a superset of a DPI. See panel-dpi.txt for the required DPI

bindings.



Required properties:

- compatible : "tpo,tpg110"

- grestb-gpios : panel reset GPIO

- scen-gpios : serial control enable GPIO

- scl-gpios : serial control clock line GPIO

- sda-gpios : serial control data line GPIO



Required nodes:

- Video port for DPI input, see panel-dpi.txt

- Panel timing for DPI setup, see panel-dpi.txt



Example

-------



panel {

	compatible = "tpo,tpg110", "panel-dpi";

	grestb-gpios = <&stmpe_gpio44 5 GPIO_ACTIVE_LOW>;

	scen-gpios = <&gpio0 6 GPIO_ACTIVE_LOW>;

	scl-gpios = <&gpio0 5 GPIO_ACTIVE_HIGH>;

	sda-gpios = <&gpio0 4 GPIO_ACTIVE_HIGH>;

	backlight = <&bl>;



	port {

		nomadik_clcd_panel: endpoint {

			remote-endpoint = <&nomadik_clcd_pads>;

		};

	};



	panel-timing {

		clock-frequency = <33200000>;

		hactive = <800>;

		hback-porch = <216>;

		hsync-len = <1>;

		vactive = <480>;

		vback-porch = <35>;

		vfront-porch = <10>;

		vsync-len = <1>;

	};

};
