-Mitsubishi AA121TD01 LVDS Display Panel
-=======================================
-
-The AA121TD01 is a 12.1" WXGA TFT-LCD display panel.
-
-These DT bindings follow the LVDS panel bindings defined in panel-lvds.txt
-with the following device-specific properties.
-
-
-Required properties:
-
-- compatible: Shall contain "mitsubishi,aa121td01" and "panel-lvds", in that
-  order.
-- vcc-supply: Reference to the regulator powering the panel VCC pins.
-
-
-Example
--------
-
-panel {
-	compatible = "mitsubishi,aa121td01", "panel-lvds";
-	vcc-supply = <&vcc_3v3>;
-
-	width-mm = <261>;
-	height-mm = <163>;
-
-	data-mapping = "jeida-24";
-
-	panel-timing {
-		/* 1280x800 @60Hz */
-		clock-frequency = <71000000>;
-		hactive = <1280>;
-		vactive = <800>;
-		hsync-len = <70>;
-		hfront-porch = <20>;
-		hback-porch = <70>;
-		vsync-len = <5>;
-		vfront-porch = <3>;
-		vback-porch = <15>;
-	};
-
-	port {
-		panel_in: endpoint {
-			remote-endpoint = <&lvds_encoder>;
-		};
-	};
-};
