+
+This binding is compatible with the simple-panel binding, which is specified
+in simple-panel.txt in this directory.
+
+Required properties:
+- compatible: should be "rocktech,rk070er9427"
+
+Optional properties:
+- backlight: phandle of the backlight device attached to the panel
+
+Optional nodes:
+- Video port for LCD panel input.

+		backlight = <&backlight_lcd>;
+
+		port {
+			lcd_panel_in: endpoint {
