+Samsung s6e63m0 AMOLED LCD panel
+
+Required properties:
+  - compatible: "samsung,s6e63m0"
+  - reset-gpio: GPIO spec for reset pin
+  - vdd3-supply: VDD regulator
+  - vci-supply: VCI regulator
+  - display-timings: timings for the connected panel as described by [1]
+
+Optional properties:
+  - reset-delay: Delay in ms after adjusting reset-gpio, default 120ms
+  - power-on-delay: Delay in ms after powering on, default 25ms
+  - power-off-delay: Delay in ms before powering off, default 200ms
+  - panel-width-mm: physical panel width in mm
+  - panel-height-mm: physical panel height in mm
+
+The device node can contain one 'port' child node with one child
+'endpoint' node, according to the bindings defined in [2]. This
+node should describe panel's video bus.
+
+[1]: Documentation/devicetree/bindings/display/panel/display-timing.txt
+[2]: Documentation/devicetree/bindings/media/video-interfaces.txt
+
+Example:
+
+		s6e63m0: display@0 {
+			compatible = "samsung,s6e63m0";
+			reg = <0>;
+			reset-gpio = <&mp05 5 1>;

+			spi-max-frequency = <1000000>;

+			power-on-delay = <0>;
+			power-off-delay = <0>;
+			reset-delay = <10>;
+			panel-width-mm = <53>;
+			panel-height-mm = <89>;
+
+			display-timings {
+				timing-0 {
+					/* 480x800@...z */
+					clock-frequency = <25628040>;
+					hactive = <480>;
+					vactive = <800>;
+					hfront-porch = <16>;
+					hback-porch = <16>;
+					hsync-len = <2>;
+					vfront-porch = <28>;
+					vback-porch = <1>;
+					vsync-len = <2>;
+				};

+
+			port {
+				lcd_ep: endpoint {
+					remote-endpoint = <&fimd_ep>;
+				};
+			};
