+Maxim Integrated MAX3355 USB OTG chip
+-------------------------------------
+
+MAX3355 integrates a charge pump and comparators to enable a system with an
+integrated USB OTG dual-role transceiver to function as a USB OTG dual-role
+device.
+
+Required properties:
+- compatible: should be "maxim,max3355";
+- maxim,shdn-gpios: should contain a phandle and GPIO specifier for the GPIO pin
+ connected to the MAX3355's SHDN# pin;
+- id-gpios: should contain a phandle and GPIO specifier for the GPIO pin
+ connected to the MAX3355's ID_OUT pin.
+
+Example:
+
+ usb-otg {
+ compatible = "maxim,max3355";
+ maxim,shdn-gpios = <&gpio2 4 GPIO_ACTIVE_LOW>;
+ id-gpios = <&gpio5 31 GPIO_ACTIVE_HIGH>;
+ };
