	---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.rst>.

config USB_EHCI_ROOT_HUB_TT
	bool "Root Hub Transaction Translators"
	depends on USB_EHCI_HCD
	---help---
	  Some EHCI chips have vendor-specific extensions to integrate
	  transaction translators, so that no OHCI or UHCI companion
	  controller is needed.  It's safe to say "y" even if your
	  controller doesn't support this feature.

	  This supports the EHCI implementation that's originally
	  from ARC, and has since changed hands a few times.

config USB_EHCI_TT_NEWSCHED
	bool "Improved Transaction Translator scheduling"
	depends on USB_EHCI_HCD
	default y
	---help---
	  This changes the periodic scheduling code to fill more of the low
	  and full speed bandwidth available from the Transaction Translator
	  (TT) in USB 2.0 hubs.  Without this, only one transfer will be
	  issued in each microframe, significantly reducing the number of
	  periodic low/fullspeed transfers possible.

	  If you have multiple periodic low/fullspeed devices connected to a
	  highspeed USB hub which is connected to a highspeed USB Host
	  Controller, and some of those devices will not work correctly
	  (possibly due to "ENOSPC" or "-28" errors), say Y.  Conversely, if
	  you have only one such device and it doesn't work, you could try
	  saying N.

	  first one is used.

	  The driver consists of two modules, the "ftdi-elan" module is a
	  USB client driver that interfaces to the FTDI chip within ELAN's
	  USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
	  controller driver that talks to the OHCI controller within the
	  CardBus cards that are inserted in the U132 adapter.

	  This driver has been tested with a CardBus OHCI USB adapter, and
	  worked with a USB PEN Drive inserted into the first USB port of
	  the PCCARD. A rather pointless thing to do, but useful for testing.

	  It is safe to say M here.

config USB_SL811_HCD
	tristate "SL811HS HCD support"
	depends on HAS_IOMEM
	help
	  The SL811HS is a single-port USB controller that supports either
	  host side or peripheral side roles.  Enable this option if your
	  board has this chip, and you want to use it as a host controller.
	  If unsure, say N.

	  To compile this driver as a module, choose M here: the
	  module will be called sl811-hcd.

config USB_SL811_HCD_ISO
	bool "partial ISO support"
	depends on USB_SL811_HCD
	help
	  The driver doesn't support iso_frame_desc (yet), but for some simple
	  devices that just queue one ISO frame per URB, then ISO transfers
	  "should" work using the normal urb status fields.

	  If unsure, say N.

config USB_SL811_CS
	tristate "CF/PCMCIA support for SL811HS HCD"
	depends on USB_SL811_HCD && PCMCIA
	help
	  Wraps a PCMCIA driver around the SL811HS HCD, supporting the RATOC
	  REX-CFU1U CF card (often used with PDAs).  If unsure, say N.

	  To compile this driver as a module, choose M here: the
	  module will be called "sl811_cs".

config USB_R8A66597_HCD
	tristate "R8A66597 HCD support"
	depends on HAS_IOMEM
	help
	  The R8A66597 is a USB 2.0 host and peripheral controller.

	  Enable this option if your board has this chip, and you want
	  to use it as a host controller.  If unsure, say N.

	  To compile this driver as a module, choose M here: the
	  module will be called r8a66597-hcd.

config USB_RENESAS_USBHS_HCD
	tristate "Renesas USBHS HCD support"
	depends on USB_RENESAS_USBHS
	help
	  The Renesas USBHS is a USB 2.0 host and peripheral controller.

	  Enable this option if your board has this chip, and you want
	  to use it as a host controller.  If unsure, say N.

	  To compile this driver as a module, choose M here: the
	  module will be called renesas-usbhs.

config USB_IMX21_HCD
	tristate "i.MX21 HCD support"
	depends on ARM && ARCH_MXC
	help
	  This driver enables support for the on-chip USB host in the
	  i.MX21 processor.

	  To compile this driver as a module, choose M here: the
	  module will be called "imx21-hcd".

config USB_HCD_BCMA
	tristate "BCMA usb host driver"
	depends on BCMA
	select USB_OHCI_HCD_PLATFORM if USB_OHCI_HCD
	select USB_EHCI_HCD_PLATFORM if USB_EHCI_HCD
	help
	  Enable support for the EHCI and OCHI host controller on an bcma bus.
	  It converts the bcma driver into two platform device drivers
	  for ehci and ohci.

	  If unsure, say N.

config USB_HCD_SSB
	tristate "SSB usb host driver"
	depends on SSB
	select USB_OHCI_HCD_PLATFORM if USB_OHCI_HCD
	select USB_EHCI_HCD_PLATFORM if USB_EHCI_HCD
	help
	  Enable support for the EHCI and OCHI host controller on an bcma bus.
	  It converts the bcma driver into two platform device drivers
	  for ehci and ohci.

	  If unsure, say N.

config USB_HCD_TEST_MODE
	bool "HCD test mode support"
	---help---
	  Say 'Y' to enable additional software test modes that may be
	  supported by the host controller drivers.

	  One such test mode is the Embedded High-speed Host Electrical Test
	  (EHSET) for EHCI host controller hardware, specifically the "Single
	  Step Set Feature" test.  Typically this will be enabled for On-the-Go
	  or embedded hosts that need to undergo USB-IF compliance testing with
	  the aid of special testing hardware.  In the future, this may expand
	  to include other tests that require support from a HCD driver.

	  This option is of interest only to developers who need to validate
	  their USB hardware designs.  It is not needed for normal use.  If
	  unsure, say N.
