+GPIO VBus phy
+=============
+
+gpio-vbus is a phy controller supporting VBus detection and pullup activation on
+GPIOs.
+
+Required properties:
+- compatible : should be "generic,phy-gpio-vbus"
+- #phy-cells : from the generic PHY bindings, must be 1.
+- gpios : set of 2 gpio properties (see gpio.txt for gpio properties format)
+ first gpio is required, it's the VBus sensing input gpio
+ second gpio is optional, it's the D+ pullup controlling output
+ gpio
+
+Optional properties:
+- wakeup : boolean, if true the VBus gpio will wakeup the platform
+
+Example:
+ usb2phy : gpio-vbus@13 {
+ compatible = "generic,phy-gpio-vbus";
+ gpios = <&gpio 13 GPIO_ACTIVE_LOW>;
+ wakeup;
+ };
