Implements OTG Finite State Machine as specified in On-The-Go
and Embedded Host Supplement to the USB Revision 2.0 Specification.
+config USB_ULPI_BUS
+ tristate "USB ULPI PHY interface support"
+ depends on USB_SUPPORT
+ help
+ UTMI+ Low Pin Interface (ULPI) is specification for a commonly used
+ USB 2.0 PHY interface. The ULPI specification defines a standard set
+ of registers that can be used to detect the vendor and product which
+ allows ULPI to be handled as a bus. This module is the driver for that
+ bus.
+
+ The ULPI interfaces (the buses) are registered by the drivers for USB
+ controllers which support ULPI register access and have ULPI PHY
+ attached to them. The ULPI PHY drivers themselves are normal PHY
+ drivers.
+
+ ULPI PHYs provide often functions such as ADP sensing/probing (OTG
+ protocol) and USB charger detection.
+
+ To compile this driver as a module, choose M here: the module will
+ be called ulpi.
