22	  UTMI+ Low Pin Interface (ULPI) is specification for a commonly used
23	  USB 2.0 PHY interface. The ULPI specification defines a standard set
24	  of registers that can be used to detect the vendor and product which
25	  allows ULPI to be handled as a bus. This module is the driver for that
26	  bus.
27
28	  The ULPI interfaces (the buses) are registered by the drivers for USB
29	  controllers which support ULPI register access and have ULPI PHY
30	  attached to them. The ULPI PHY drivers themselves are normal PHY
31	  drivers.
32
33	  ULPI PHYs provide often functions such as ADP sensing/probing (OTG
34	  protocol) and USB charger detection.

36	  To compile this driver as a module, choose M here: the module will
37	  be called ulpi.

43	help
44	  The driver supports USB role switch between host and device via GPIO
45	  based USB cable detection, used typically if an input GPIO is used
46	  to detect USB ID pin, and another input GPIO may be also used to detect
47	  Vbus pin at the same time, it also can be used to enable/disable
48	  device if an input GPIO is only used to detect Vbus pin.

50	  To compile the driver as a module, choose M here: the module will
51	  be called usb-conn-gpio.ko
