    +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>;
    + };
    + };
