Select this to make sure the build includes objects from
the OTG infrastructure directory.

config USB_GPIO_VBUS
tristate "GPIO based peripheral-only VBUS sensing 'transceiver'"
depends on GENERIC_GPIO
select USB_OTG_UTILS
help
Provides simple GPIO VBUS sensing for controllers with an
internal transceiver via the otg_transceiver interface, and
optionally control of a D+ pullup GPIO as well as a VBUS
current limit regulator.
config ISP1301_OMAP
tristate "Philips ISP1301 with OMAP OTG"
depends on I2C && ARCH_OMAP_OTG
select USB_OTG_UTILS
help
If you say yes here you get support for the Philips ISP1301
USB-On-The-Go transceiver working with the OMAP OTG controller.
The ISP1301 is a full speed USB transceiver which is used in
products including H2, H3, and H4 development boards for Texas
Instruments OMAP processors.
This driver can also be built as a module. If so, the module
will be called isp1301_omap.
config USB_ULPI
bool "Generic ULPI Transceiver Driver"
depends on ARM
select USB_OTG_UTILS
help
Enable this to support ULPI connected USB OTG transceivers which
are likely found on embedded boards.
config USB_ULPI_VIEWPORT
bool
depends on USB_ULPI
help
Provides read/write operations to the ULPI phy register set for
controllers with a viewport register (e.g. Chipidea/ARC controllers).
config TWL4030_USB
tristate "TWL4030 USB Transceiver Driver"
depends on TWL4030_CORE && REGULATOR_TWL4030
select USB_OTG_UTILS
help
Enable this to support the USB OTG transceiver on TWL4030
family chips (including the TWL5030 and TPS659x0 devices).
This transceiver supports high and full speed devices plus,
in host mode, low speed.
config TWL6030_USB
tristate "TWL6030 USB Transceiver Driver"
depends on TWL4030_CORE
select USB_OTG_UTILS
help
Enable this to support the USB OTG transceiver on TWL6030
family chips. This TWL6030 transceiver has the VBUS and ID GND
and OTG SRP events capabilities. For all other transceiver functionality
UTMI PHY is embedded in OMAP4430. The internal PHY configurations APIs
are hooked to this driver through platform_data structure.
The definition of internal PHY APIs are in the mach-omap2 layer.
config NOP_USB_XCEIV
tristate "NOP USB Transceiver Driver"
select USB_OTG_UTILS
help
this driver is to be used by all the usb transceiver which are either
built-in with usb ip or which are autonomous and doesn't require any
phy programming such as ISP1x04 etc.
config USB_LANGWELL_OTG
tristate "Intel Langwell USB OTG dual-role support"
depends on USB && PCI && INTEL_SCU_IPC
select USB_OTG
select USB_OTG_UTILS
help
Say Y here if you want to build Intel Langwell USB OTG
transciever driver in kernel. This driver implements role
switch between EHCI host driver and Langwell USB OTG
client driver.
To compile this driver as a module, choose M here: the
module will be called langwell_otg.
config USB_MSM_OTG
tristate "OTG support for Qualcomm on-chip USB controller"
depends on (USB || USB_GADGET) && ARCH_MSM
select USB_OTG_UTILS
help
Enable this to support the USB OTG transceiver on MSM chips. It
handles PHY initialization, clock management, and workarounds
required after resetting the hardware and power management.
This driver is required even for peripheral only or host only
mode configurations.
This driver is not supported on boards like trout which
has an external PHY.
config AB8500_USB
tristate "AB8500 USB Transceiver Driver"
depends on AB8500_CORE
select USB_OTG_UTILS
help
Enable this to support the USB OTG transceiver in AB8500 chip.
This transceiver supports high and full speed devices plus,
in host mode, low speed.
