Changes from v2:
  - Added Reviewed-by

Changes from v1:
  - Add missing subject prefix
  - Rename reset-gpio to reset-gpios
  - Add link to spi properites documentation. They're required
    for driver to work
  - Removed delay properties, which are now hardcoded in driver
  - Removed display timings, which are now hardcoded in driver

+Samsung s6e63m0 AMOLED LCD panel
+
+Required properties:
+  - compatible: "samsung,s6e63m0"
+  - reset-gpios: GPIO spec for reset pin
+  - vdd3-supply: VDD regulator
+  - vci-supply: VCI regulator
+
+The panel must obey rules for SPI slave device specified in document [1].
+
+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.
+

+Example:
+
+		s6e63m0: display@0 {
+			compatible = "samsung,s6e63m0";
+			reg = <0>;
+			reset-gpio = <&mp05 5 1>;
+			vdd3-supply = <&ldo12_reg>;
+			vci-supply = <&ldo11_reg>;
+			spi-max-frequency = <1200000>;
+
+			port {
+				lcd_ep: endpoint {
+					remote-endpoint = <&fimd_ep>;
+				};
+			};
