+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";

+                       vci-supply = <&ldo11_reg>;
+                       spi-max-frequency = <1200000>;
+
+                       port {
+                               lcd_ep: endpoint {
