+TBD: Add support for multiple connectors
+
+An example node with multiple connectors might look as follows.
+
+ some-connector {
+ #size-cells = <1>;
+ compatible = "gpio-connector";
+ presence-detect-gpios = <&gpio1 7 1>;
+ id-gpios = <&gpio1 8 0>;

+This describes a cable with a (low-active) presence detect pin and an ID pin.
+If the value returned by the ID pin is 0, the connected cable type is "USB".
+If the value is 1, the connected cable type is "USB-Host".
