config USB_EHCI_HCD
	bool "EHCI HCD (USB 2.0) support"
	default y if ARCH_MX5 || ARCH_MX6
	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.

	---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.

	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.
