Say Y here if you are working on a system with led-class supported

|
LEDs and you want to use them as activity indicators for USB host or

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.
