8 tristate "Cypress C67x00 HCD support"
11 The Cypress C67x00 (EZ-Host/EZ-OTG) chips are dual-role
12 host/peripheral/OTG USB controllers.
14 Enable this option to support this chip in host controller mode.
17 To compile this driver as a module, choose M here: the
18 module will be called c67x00.
21 tristate "xHCI HCD (USB 3.0) support (EXPERIMENTAL)"
22 depends on USB && PCI && EXPERIMENTAL
24 The eXtensible Host Controller Interface (xHCI) is standard for USB 3.0
25 "SuperSpeed" host controller hardware.
27 To compile this driver as a module, choose M here: the
28 module will be called xhci-hcd.
30 config USB_XHCI_HCD_DEBUGGING
31 bool "Debugging for the xHCI host controller"
32 depends on USB_XHCI_HCD
34 Say 'Y' to turn on debugging for the xHCI host controller driver.
35 This will spew debugging output, even in interrupt context.
36 This should only be used for debugging xHCI driver bugs.
41 tristate "EHCI HCD (USB 2.0) support"
42 depends on USB && USB_ARCH_HAS_EHCI
44 The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
45 "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
46 If your USB host controller supports USB 2.0, you will likely want to
47 configure this Host Controller Driver.
49 EHCI controllers are packaged with "companion" host controllers (OHCI
50 or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
51 will connect to EHCI if the device is high speed, otherwise they
52 connect to a companion controller. If you configure EHCI, you should
53 probably configure the OHCI (for NEC and some other vendors) USB Host
54 Controller Driver or UHCI (for Via motherboards) Host Controller
57 You may want to read <file:Documentation/usb/ehci.txt>.
59 To compile this driver as a module, choose M here: the
60 module will be called ehci-hcd.
62 config USB_EHCI_ROOT_HUB_TT
63 bool "Root Hub Transaction Translators"
64 depends on USB_EHCI_HCD
66 Some EHCI chips have vendor-specific extensions to integrate
67 transaction translators, so that no OHCI or UHCI companion
68 controller is needed. It's safe to say "y" even if your
69 controller doesn't support this feature.
71 This supports the EHCI implementation that's originally
72 from ARC, and has since changed hands a few times.
74 config USB_EHCI_TT_NEWSCHED
75 bool "Improved Transaction Translator scheduling (EXPERIMENTAL)"
76 depends on USB_EHCI_HCD && EXPERIMENTAL
78 This changes the periodic scheduling code to fill more of the low
79 and full speed bandwidth available from the Transaction Translator
80 (TT) in USB 2.0 hubs. Without this, only one transfer will be
81 issued in each microframe, significantly reducing the number of
82 periodic low/fullspeed transfers possible.
84 If you have multiple periodic low/fullspeed devices connected to a
85 highspeed USB hub which is connected to a highspeed USB Host
86 Controller, and some of those devices will not work correctly
87 (possibly due to "ENOSPC" or "-28" errors), say Y.
91 config USB_EHCI_BIG_ENDIAN_MMIO
93 depends on USB_EHCI_HCD && (PPC_CELLEB || PPC_PS3 || 440EPX || ARCH_IXP4XX)
96 config USB_EHCI_BIG_ENDIAN_DESC
98 depends on USB_EHCI_HCD && (440EPX || ARCH_IXP4XX)
102 bool "Support for Freescale on-chip EHCI USB controller"
103 depends on USB_EHCI_HCD && FSL_SOC
104 select USB_EHCI_ROOT_HUB_TT
106 Variation of ARC USB block used in some Freescale chips.
108 config USB_EHCI_HCD_PPC_OF
109 bool "EHCI support for PPC USB controller on OF platform bus"
110 depends on USB_EHCI_HCD && PPC_OF
113 Enables support for the USB controller present on the PowerPC
114 OpenFirmware platform bus.
116 config USB_W90X900_EHCI
117 bool "W90X900(W90P910) EHCI support"
118 depends on USB_EHCI_HCD && ARCH_W90X900
120 Enables support for the W90X900 USB controller
122 config USB_OXU210HP_HCD
123 tristate "OXU210HP HCD support"
126 The OXU210HP is an USB host/OTG/device controller. Enable this
127 option if your board has this chip. If unsure, say N.
129 This driver does not support isochronous transfers and doesn't
130 implement OTG nor USB device controllers.
132 To compile this driver as a module, choose M here: the
133 module will be called oxu210hp-hcd.
135 config USB_ISP116X_HCD
136 tristate "ISP116X HCD support"
139 The ISP1160 and ISP1161 chips are USB host controllers. Enable this
140 option if your board has this chip. If unsure, say N.
142 This driver does not support isochronous transfers.
144 To compile this driver as a module, choose M here: the
145 module will be called isp116x-hcd.
147 config USB_ISP1760_HCD
148 tristate "ISP 1760 HCD support"
149 depends on USB && EXPERIMENTAL
151 The ISP1760 chip is a USB 2.0 host controller.
153 This driver does not support isochronous transfers or OTG.
154 This USB controller is usually attached to a non-DMA-Master
155 capable bus. NXP's eval kit brings this chip on PCI card
156 where the chip itself is behind a PLB to simulate such
159 To compile this driver as a module, choose M here: the
160 module will be called isp1760.
162 config USB_ISP1362_HCD
163 tristate "ISP1362 HCD support"
167 Supports the Philips ISP1362 chip as a host controller
169 This driver does not support isochronous transfers.
171 To compile this driver as a module, choose M here: the
172 module will be called isp1362-hcd.
175 tristate "OHCI HCD support"
176 depends on USB && USB_ARCH_HAS_OHCI
177 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3
178 select USB_OTG_UTILS if ARCH_OMAP
180 The Open Host Controller Interface (OHCI) is a standard for accessing
181 USB 1.1 host controller hardware. It does more in hardware than Intel's
182 UHCI specification. If your USB host controller follows the OHCI spec,
183 say Y. On most non-x86 systems, and on x86 hardware that's not using a
184 USB controller from Intel or VIA, this is appropriate. If your host
185 controller doesn't use PCI, this is probably appropriate. For a PCI
186 based system where you're not sure, the "lspci -v" entry will list the
187 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
189 To compile this driver as a module, choose M here: the
190 module will be called ohci-hcd.
192 config USB_OHCI_HCD_PPC_SOC

216 Enables support for little-endian USB controllers present on the
217 OpenFirmware platform bus.

224 config USB_OHCI_HCD_PCI
225 bool "OHCI support for PCI-bus USB controllers"
226 depends on USB_OHCI_HCD && PCI && (STB03xxx || PPC_MPC52xx || USB_OHCI_HCD_PPC_OF)
228 select USB_OHCI_LITTLE_ENDIAN
230 Enables support for PCI-bus plug-in USB controller cards.

263 tristate "UHCI HCD (most Intel and VIA) support"
264 depends on USB && PCI
266 The Universal Host Controller Interface is a standard by Intel for
267 accessing the USB hardware in the PC (which is also called the USB
268 host controller). If your USB host controller conforms to this
269 standard, you may want to say Y, but see below. All recent boards
270 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
271 i810, i820) conform to this standard. Also all VIA PCI chipsets
272 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
273 133). If unsure, say Y.

276 module will be called uhci-hcd.

285 (as found on MPC8360 and MPC8323 processors), the driver supports
286 Full and Low Speed USB.
289 bool "Freescale QE USB Host Controller debug support"
290 depends on USB_FHCI_HCD && DEBUG_FS
292 Say "y" to see some FHCI debug information and statistics
296 tristate "Elan U132 Adapter Host Controller"
297 depends on USB && USB_FTDI_ELAN
300 The U132 adapter is a USB to CardBus adapter specifically designed
301 for PC cards that contain an OHCI host controller. Typical PC cards
302 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
303 adapter will *NOT* work with PC cards that do not contain an OHCI
306 For those PC cards that contain multiple OHCI controllers only the
309 The driver consists of two modules, the "ftdi-elan" module is a
310 USB client driver that interfaces to the FTDI chip within ELAN's
311 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
312 controller driver that talks to the OHCI controller within the
313 CardBus cards that are inserted in the U132 adapter.
315 This driver has been tested with a CardBus OHCI USB adapter, and
316 worked with a USB PEN Drive inserted into the first USB port of
317 the PCCARD. A rather pointless thing to do, but useful for testing.
319 It is safe to say M here.

324 tristate "SL811HS HCD support"

328 host side or peripheral side roles. Enable this option if your
329 board has this chip, and you want to use it as a host controller.
332 To compile this driver as a module, choose M here: the
333 module will be called sl811-hcd.
336 tristate "CF/PCMCIA support for SL811HS HCD"

339 Wraps a PCMCIA driver around the SL811HS HCD, supporting the RATOC
340 REX-CFU1U CF card (often used with PDAs). If unsure, say N.
342 To compile this driver as a module, choose M here: the
343 module will be called "sl811_cs".
