9	depends on USB
10	help
11	  The Cypress C67x00 (EZ-Host/EZ-OTG) chips are dual-role
12	  host/peripheral/OTG USB controllers.
13
14	  Enable this option to support this chip in host controller mode.
15	  If unsure, say N.

20config USB_EHCI_HCD
21	tristate "EHCI HCD (USB 2.0) support"
22	depends on USB && USB_ARCH_HAS_EHCI
23	---help---
24	  The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
25	  "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
26	  If your USB host controller supports USB 2.0, you will likely want to
27	  configure this Host Controller Driver.  At the time of this writing,
28	  the primary implementation of EHCI is a chip from NEC, widely available
29	  in add-on PCI cards, but implementations are in the works from other
30	  vendors including Intel and Philips.  Motherboard support is appearing.
31
32	  EHCI controllers are packaged with "companion" host controllers (OHCI
33	  or UHCI) to handle USB 1.1 devices connected to root hub ports.  Ports
34	  will connect to EHCI if the device is high speed, otherwise they
35	  connect to a companion controller.  If you configure EHCI, you should
36	  probably configure the OHCI (for NEC and some other vendors) USB Host
37	  Controller Driver or UHCI (for Via motherboards) Host Controller
38	  Driver too.
39
40	  You may want to read <file:Documentation/usb/ehci.txt>.
41
42	  To compile this driver as a module, choose M here: the
43	  module will be called ehci-hcd.

45config USB_EHCI_ROOT_HUB_TT
46	bool "Root Hub Transaction Translators"
47	depends on USB_EHCI_HCD
48	---help---
49	  Some EHCI chips have vendor-specific extensions to integrate
50	  transaction translators, so that no OHCI or UHCI companion
51	  controller is needed.  It's safe to say "y" even if your
52	  controller doesn't support this feature.
53
54	  This supports the EHCI implementation that's originally
55	  from ARC, and has since changed hands a few times.
56
57config USB_EHCI_TT_NEWSCHED
58	bool "Improved Transaction Translator scheduling (EXPERIMENTAL)"
59	depends on USB_EHCI_HCD && EXPERIMENTAL
60	---help---
61	  This changes the periodic scheduling code to fill more of the low
62	  and full speed bandwidth available from the Transaction Translator
63	  (TT) in USB 2.0 hubs.  Without this, only one transfer will be
64	  issued in each microframe, significantly reducing the number of
65	  periodic low/fullspeed transfers possible.
66
67	  If you have multiple periodic low/fullspeed devices connected to a
68	  highspeed USB hub which is connected to a highspeed USB Host
69	  Controller, and some of those devices will not work correctly
70	  (possibly due to "ENOSPC" or "-28" errors), say Y.
71

143	  The Open Host Controller Interface (OHCI) is a standard for accessing
144	  USB 1.1 host controller hardware.  It does more in hardware than Intel's
145	  UHCI specification.  If your USB host controller follows the OHCI spec,
146	  say Y.  On most non-x86 systems, and on x86 hardware that's not using a
147	  USB controller from Intel or VIA, this is appropriate.  If your host
148	  controller doesn't use PCI, this is probably appropriate.  For a PCI
149	  based system where you're not sure, the "lspci -v" entry will list the
150	  right "prog-if" for your USB controller(s):  EHCI, OHCI, or UHCI.

228	  The Universal Host Controller Interface is a standard by Intel for
229	  accessing the USB hardware in the PC (which is also called the USB
230	  host controller). If your USB host controller conforms to this
231	  standard, you may want to say Y, but see below. All recent boards
232	  with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
233	  i810, i820) conform to this standard. Also all VIA PCI chipsets
234	  (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
235	  133). If unsure, say Y.

243	default M
244	help
245	  The U132 adapter is a USB to CardBus adapter specifically designed
246	  for PC cards that contain an OHCI host controller. Typical PC cards
247	  are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
248	  adapter will *NOT* work with PC cards that do not contain an OHCI
249	  controller.
250
251	  For those PC cards that contain multiple OHCI controllers only the
252	  first one is used.
253
254	  The driver consists of two modules, the "ftdi-elan" module is a
255	  USB client driver that interfaces to the FTDI chip within ELAN's
256	  USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
257	  controller driver that talks to the OHCI controller within the
258	  CardBus cards that are inserted in the U132 adapter.
259
260	  This driver has been tested with a CardBus OHCI USB adapter, and
261	  worked with a USB PEN Drive inserted into the first USB port of
262	  the PCCARD. A rather pointless thing to do, but useful for testing.
263
264	  It is safe to say M here.
