The purpose of USB Type-C connector class is to provide unified interface for the user space to get the status and basic information about USB Type-C connectors on a system, control over data role swapping, and when the port supports USB Power Delivery, also control over power role swapping and Alternate Modes.

config USB tristate "Support for Host-side USB" depends on USB_ARCH_HAS_HCD select USB_COMMON select NLS # for UTF-8 strings ---help--- Universal Serial Bus (USB) is a specification for a serial bus subsystem which offers higher speeds and more features than the traditional PC serial port. The bus supplies power to peripherals and allows for hot swapping. Up to 127 USB peripherals can be connected to a single USB host in a tree structure.
The USB host is the root of the tree, the peripherals are the
leaves and the inner nodes are special USB devices called hubs.
Most PCs now have USB host ports, used to connect peripherals
such as scanners, keyboards, mice, modems, cameras, disks,
flash memory, network links, and printers to the PC.
Say Y here if your computer has a host-side USB port and you want
to use USB devices. You then need to say Y to at least one of the
Host Controller Driver (HCD) options below. Choose a USB 1.1
controller, such as "UHCI HCD support" or "OHCI HCD support",
and "EHCI HCD (USB 2.0) support" except for older systems that
do not have USB 2.0 support. It doesn't normally hurt to select
them all if you are not certain.
If your system has a device-side USB port, used in the peripheral
side of the USB protocol, see the "USB Gadget" framework instead.
After choosing your HCD, then select drivers for the USB peripherals
you'll be using. You may want to check out the information provided
in <file:Documentation/usb/> and especially the links given in
<file:Documentation/usb/usb-help.txt>.
To compile this driver as a module, choose M here: the
module will be called usbcore.
config USB_PCI bool "PCI based USB host interface" depends on PCI default y ---help--- A lot of embeded system SOC (e.g. freescale T2080) have both PCI and USB modules. But USB module is controlled by registers directly, it have no relationship with PCI module.
When say N here it will not build PCI related code in USB driver.

config USB_USS720 tristate "USS720 parport driver" depends on PARPORT select PARPORT_NOT_PC ---help--- This driver is for USB parallel port adapters that use the Lucent Technologies USS-720 chip. These cables are plugged into your USB port and provide USB compatibility to peripherals designed with parallel port interfaces.
The chip has two modes: automatic mode and manual mode. In automatic
mode, it looks to the computer like a standard USB printer. Only
printers may be connected to the USS-720 in this mode. The generic
USB printer driver ("USB Printer support", above) may be used in
that mode, and you can say N here if you want to use the chip only
in this mode.
Manual mode is not limited to printers, any parallel port
device should work. This driver utilizes manual mode.
Note however that some operations are three orders of magnitude
slower than on a PCI/ISA Parallel Port, so timing critical
applications might not work.
Say Y here if you own an USS-720 USB->Parport cable and intend to
connect anything other than a printer to it.
To compile this driver as a module, choose M here: the
module will be called uss720.

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.
