	help
	  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.
