This reverts commitcb9c1cfc86for USB_LED_TRIG. This config symbol has bool type and enables extra code in usb_common itself, not a separate driver. Enabling it should not force usb_common to be built-in!

This option adds LED triggers for USB host and/or gadget activity.

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
|
|
gadget.

|
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.

help
|
|
The driver supports USB role switch between host and device via GPIO
|
|
based USB cable detection, used typically if an input GPIO is used
|
|
to detect USB ID pin, and another input GPIO may be also used to detect
|
|
Vbus pin at the same time, it also can be used to enable/disable
|
|
device if an input GPIO is only used to detect Vbus pin.
|
|
|
|
To compile the driver as a module, choose M here: the module will
|
|
be called usb-conn-gpio.ko
