+Mitsubishi AA204XD12 LVDS Display Panel
+=======================================
+
+The AA104XD12 is a 10.4" XGA 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,aa104xd12", "panel-lvds";
+	vcc-supply = <&vcc_3v3>;
+
+	width-mm = <210>;
+	height-mm = <158>;
+
+	data-mapping = "jeida-24";
+
+	panel-timing {
+		/* 1024x768 @65Hz */
+		clock-frequency = <65000000>;
+		hactive = <1024>;
+		vactive = <768>;
+		hsync-len = <136>;
+		hfront-porch = <20>;
+		hback-porch = <160>;
+		vfront-porch = <3>;
+		vback-porch = <29>;
+		vsync-len = <6>;

+		panel_in: endpoint {
+			remote-endpoint = <&lvds_encoder>;
+		};

+Mitsubishi AA121TD01 LVDS Display Panel
+=======================================
