The eXtensible Host Controller Interface (xHCI) is standard for USB 3.0
"SuperSpeed" host controller hardware.
if USB_XHCI_HCD

Say Y or if your system has a Dual Role SuperSpeed
USB controller based on the DesignWare USB3 IP Core.

select USB_HOST
---help---
The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
"high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
If your USB host controller supports USB 2.0, you will likely want to
configure this Host Controller Driver.
EHCI controllers are packaged with "companion" host controllers (OHCI
or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
will connect to EHCI if the device is high speed, otherwise they
connect to a companion controller. If you configure EHCI, you should
probably configure the OHCI (for NEC and some other vendors) USB Host
Controller Driver or UHCI (for Via motherboards) Host Controller
Driver too.
You may want to read <file:Documentation/usb/ehci.txt>.

---help---
The Open Host Controller Interface (OHCI) is a standard for accessing
USB 1.1 host controller hardware. It does more in hardware than Intel's
UHCI specification. If your USB host controller follows the OHCI spec,
say Y. On most non-x86 systems, and on x86 hardware that's not using a
USB controller from Intel or VIA, this is appropriate. If your host
controller doesn't use PCI, this is probably appropriate. For a PCI
based system where you're not sure, the "lspci -v" entry will list the
right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
if USB_OHCI_HCD
config USB_OHCI_GENERIC
bool "Support for generic OHCI USB controller"
depends on OF_CONTROL
depends on DM_USB
select USB_HOST
---help---
Enables support for generic OHCI controller.
endif # USB_OHCI_HCD
config USB_UHCI_HCD
bool "UHCI HCD (most Intel and VIA) support"
select USB_HOST
---help---
The Universal Host Controller Interface is a standard by Intel for
accessing the USB hardware in the PC (which is also called the USB
host controller). If your USB host controller conforms to this
standard, you may want to say Y, but see below. All recent boards
with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
i810, i820) conform to this standard. Also all VIA PCI chipsets
(like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
133) and LEON/GRLIB SoCs with the GRUSBHC controller.
If unsure, say Y.
