+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.

+ reset-delay = <10>;
+ panel-width-mm = <53>;
+ panel-height-mm = <89>;
+
+ display-timings {
+ timing-0 {
+ /* 480x800 at 60Hz */
+ clock-frequency = <25628040>;
+ hactive = <480>;
+ vactive = <800>;
+ hfront-porch = <16>;
+ hback-porch = <16>;
+ hsync-len = <2>;
+ vfront-porch = <28>;
