+Kaohsiung Opto-Electronics. TX31D200VM0BAA 12.3" HSXGA LVDS panel
+
+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>;
+                       };
+               };
