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>;
+ };
+ };
