+-----------------------
+
+The Analogix ANX7808 is a HDMI to MyDP (video over micro-USB) bridge chip.
+
+
+Required properties:
+       - compatible: "analogix,anx7808"
+       - reg: first i2c address of the bridge
+       - pd-gpio: OF device-tree gpio specification of the power down pin
+       - reset-gpio: OF device-tree gpio specification of the reset pin
+       - cable-det-gpio: OF device-tree gpio specification of the cable
+         detect pin
+       - intp-gpio: OF device-tree gpio specification of the external
+         interrupt pin
+
+Example:
+anx7808-bridge@38 {
+       compatible = "analogix,anx7808";
+       reg = <0x38>;
+       pd-gpio = <&gpe0 6 1 0 0>;
+       reset-gpio = <&gpe0 7 1 0 0>;
+       cable-det-gpio = <&gpx0 7 0 0 0>;
+       intp-gpio = <&gpf0 0 0 0 0>;
+};
