+AU Optronics Corporation 7.0" FHD (800 x 480) TFT LCD panel
+
+Required properties:
+- compatible: should be "auo,g070vvn01"
+- backlight: phandle of the backlight device attached to the panel
+- power-supply: single regulator to provide the supply voltage
+
+Required nodes:
+- port: Parallel port mapping to connect this display
+
+This panel needs single power supply voltage. Its backlight is conntrolled
+via PWM signal.
+
+Example:
+--------
+
+Example device-tree definition when connected to iMX6Q based board

+ compatible = "auo,g070vvn01";
+ backlight = <&backlight_lcd>;
+ power-supply = <®_display>;
+
+ port {
