+ USB Role Switch is a device that can select the USB role - host or
+ device - for a USB port (connector). In most cases dual-role capable
+ USB controller will also represent the switch, but on some platforms
+ multiplexer/demultiplexer switch is used to route the data lines on
+ the USB connector between separate USB host and device controllers.
+
+ Say Y here if your USB connectors support both device and host roles.
+ To compile the driver as module, choose M here: the module will be
+ called roles.ko.
