+Device-Tree bindings for extcon/extcon-gpio driver
+
+Required properties:
+	- compatible = "gpio-connector";
+	- presence-detect-gpios - presence detect gpio pin
+
+Optional properties:
+	- debounce-interval - debounce interval in milli-seconds
+	- state-on - on (connected) state
+	- state-off - off (disconnected) state
+	  Depending on the type of connector or cable, states may
+	  for example be reported as "connected"/"disconnected"
+	  or "inserted"/"removed".
+
+Example node:
+
+	some-connector {
+		compatible = "gpio-connector";
+		presence-detect-gpios = <&gpio1 7 1>;
+		debounce-interval = <1>;
+		state-on = "connected";
+		state-on = "disconnected";
+	};
