config USB_COMMON
tristate
config USB_LED_TRIG
bool "USB LED Triggers"
depends on LEDS_CLASS && USB_COMMON && LEDS_TRIGGERS
help
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.
config USB_ULPI_BUS
tristate "USB ULPI PHY interface support"
select USB_COMMON
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.
config USB_CONN_GPIO
tristate "USB GPIO Based Connection Detection Driver"
depends on GPIOLIB
select USB_ROLE_SWITCH
select POWER_SUPPLY
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
