+This binding is compatible with the simple-panel binding, which is specified
+in simple-panel.txt in this directory.
+
+Required properties:
+- compatible: should be "koe,tx31d200vm0baa"
+
+Optional properties:
+- backlight: phandle of the backlight device attached to the panel
+
+Optional nodes:
+- Video port for LVDS panel input.
+
+Example:
+ panel {
+ compatible = "koe,tx31d200vm0baa";
+ backlight = <&backlight_lvds>;
+
+ port {
+ panel_in: endpoint {
+ remote-endpoint = <&lvds0_out>;
+ };
+ };
+ };
