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.

			vdd3-supply = <&ldo12_reg>;
			vci-supply = <&ldo11_reg>;
			spi-max-frequency = <1200000>;

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