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 "EHCI HCD (USB 2.0) support"
22 depends on USB && USB_ARCH_HAS_EHCI
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.
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
40 You may want to read <file:Documentation/usb/ehci.txt>.
42 To compile this driver as a module, choose M here: the
43 module will be called ehci-hcd.
46 depends on USB_EHCI_HCD && EXPERIMENTAL && ARCH_OMAP34XX
48 Choose PHY or TLL mode of operation
50 config OMAP_EHCI_PHY_MODE
51 bool "PHY mode: ISP1504 on Port1/2 (NEW 3430ES2.0)"
52 depends on USB_EHCI_HCD && EXPERIMENTAL && ARCH_OMAP34XX
54 EHCI PHY mode. Port1 and Port2 are connected to ISP1504 transcievers
56 config OMAP_EHCI_TLL_MODE
57 bool "TLL mode: (EXPERIMENTAL)"
58 depends on USB_EHCI_HCD && EXPERIMENTAL && ARCH_OMAP34XX
60 OMAP EHCI controller has TLL mode of operation for all 3 ports.
61 Use this mode when no transciever is present
64 config USB_EHCI_ROOT_HUB_TT
65 bool "Root Hub Transaction Translators"
66 depends on USB_EHCI_HCD
68 Some EHCI chips have vendor-specific extensions to integrate
69 transaction translators, so that no OHCI or UHCI companion
70 controller is needed. It's safe to say "y" even if your
71 controller doesn't support this feature.
73 This supports the EHCI implementation that's originally
74 from ARC, and has since changed hands a few times.
76 config USB_EHCI_TT_NEWSCHED
77 bool "Improved Transaction Translator scheduling (EXPERIMENTAL)"
78 depends on USB_EHCI_HCD && EXPERIMENTAL
80 This changes the periodic scheduling code to fill more of the low
81 and full speed bandwidth available from the Transaction Translator
82 (TT) in USB 2.0 hubs. Without this, only one transfer will be
83 issued in each microframe, significantly reducing the number of
84 periodic low/fullspeed transfers possible.
86 If you have multiple periodic low/fullspeed devices connected to a
87 highspeed USB hub which is connected to a highspeed USB Host
88 Controller, and some of those devices will not work correctly
89 (possibly due to "ENOSPC" or "-28" errors), say Y.

104 bool "Support for Freescale on-chip EHCI USB controller"
105 depends on USB_EHCI_HCD && FSL_SOC
106 select USB_EHCI_ROOT_HUB_TT
108 Variation of ARC USB block used in some Freescale chips.
110 config USB_EHCI_HCD_PPC_OF
111 bool "EHCI support for PPC USB controller on OF platform bus"
112 depends on USB_EHCI_HCD && PPC_OF
115 Enables support for the USB controller present on the PowerPC
116 OpenFirmware platform bus.
118 config USB_ISP116X_HCD
119 tristate "ISP116X HCD support"
122 The ISP1160 and ISP1161 chips are USB host controllers. Enable this
123 option if your board has this chip. If unsure, say N.
125 This driver does not support isochronous transfers.
127 To compile this driver as a module, choose M here: the
128 module will be called isp116x-hcd.
130 config USB_ISP1760_HCD
131 tristate "ISP 1760 HCD support"
132 depends on USB && EXPERIMENTAL && (PCI || PPC_OF)
134 The ISP1760 chip is a USB 2.0 host controller.
136 This driver does not support isochronous transfers or OTG.
137 This USB controller is usually attached to a non-DMA-Master
138 capable bus. NXP's eval kit brings this chip on PCI card
139 where the chip itself is behind a PLB to simulate such

143 module will be called isp1760.
146 tristate "OHCI HCD support"
147 depends on USB && USB_ARCH_HAS_OHCI
148 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3
150 The Open Host Controller Interface (OHCI) is a standard for accessing
151 USB 1.1 host controller hardware. It does more in hardware than Intel's
152 UHCI specification. If your USB host controller follows the OHCI spec,
153 say Y. On most non-x86 systems, and on x86 hardware that's not using a
154 USB controller from Intel or VIA, this is appropriate. If your host
155 controller doesn't use PCI, this is probably appropriate. For a PCI
156 based system where you're not sure, the "lspci -v" entry will list the
157 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
159 To compile this driver as a module, choose M here: the
160 module will be called ohci-hcd.
162 config USB_OHCI_HCD_PPC_SOC

164 depends on USB_OHCI_HCD && (STB03xxx || PPC_MPC52xx)
166 select USB_OHCI_BIG_ENDIAN_DESC
167 select USB_OHCI_BIG_ENDIAN_MMIO
169 Enables support for the USB controller on the MPC52xx or
170 STB03xxx processor chip. If unsure, say Y.
172 config USB_OHCI_HCD_PPC_OF
173 bool "OHCI support for PPC USB controller on OF platform bus"
174 depends on USB_OHCI_HCD && PPC_OF
177 Enables support for the USB controller PowerPC present on the
178 OpenFirmware platform bus.
180 config USB_OHCI_HCD_PPC_OF_BE
181 bool "Support big endian HC"
182 depends on USB_OHCI_HCD_PPC_OF
184 select USB_OHCI_BIG_ENDIAN_DESC
185 select USB_OHCI_BIG_ENDIAN_MMIO
187 config USB_OHCI_HCD_PPC_OF_LE
188 bool "Support little endian HC"
189 depends on USB_OHCI_HCD_PPC_OF
191 select USB_OHCI_LITTLE_ENDIAN
193 config USB_OHCI_HCD_PCI
194 bool "OHCI support for PCI-bus USB controllers"
195 depends on USB_OHCI_HCD && PCI && (STB03xxx || PPC_MPC52xx || USB_OHCI_HCD_PPC_OF)
197 select USB_OHCI_LITTLE_ENDIAN
199 Enables support for PCI-bus plug-in USB controller cards.

232 tristate "UHCI HCD (most Intel and VIA) support"
233 depends on USB && PCI
235 The Universal Host Controller Interface is a standard by Intel for
236 accessing the USB hardware in the PC (which is also called the USB
237 host controller). If your USB host controller conforms to this
238 standard, you may want to say Y, but see below. All recent boards
239 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
240 i810, i820) conform to this standard. Also all VIA PCI chipsets
241 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
242 133). If unsure, say Y.
244 To compile this driver as a module, choose M here: the
245 module will be called uhci-hcd.
248 tristate "Elan U132 Adapter Host Controller"
249 depends on USB && USB_FTDI_ELAN
252 The U132 adapter is a USB to CardBus adapter specifically designed
253 for PC cards that contain an OHCI host controller. Typical PC cards
254 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
255 adapter will *NOT* work with PC cards that do not contain an OHCI
258 For those PC cards that contain multiple OHCI controllers only the
261 The driver consists of two modules, the "ftdi-elan" module is a
262 USB client driver that interfaces to the FTDI chip within ELAN's
263 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
264 controller driver that talks to the OHCI controller within the
265 CardBus cards that are inserted in the U132 adapter.
267 This driver has been tested with a CardBus OHCI USB adapter, and
268 worked with a USB PEN Drive inserted into the first USB port of
269 the PCCARD. A rather pointless thing to do, but useful for testing.
271 It is safe to say M here.

280 host side or peripheral side roles. Enable this option if your
281 board has this chip, and you want to use it as a host controller.
284 To compile this driver as a module, choose M here: the
285 module will be called sl811-hcd.
288 tristate "CF/PCMCIA support for SL811HS HCD"
289 depends on USB_SL811_HCD && PCMCIA
291 Wraps a PCMCIA driver around the SL811HS HCD, supporting the RATOC
292 REX-CFU1U CF card (often used with PDAs). If unsure, say N.

301 The R8A66597 is a USB 2.0 host and peripheral controller.
303 Enable this option if your board has this chip, and you want
304 to use it as a host controller. If unsure, say N.
306 To compile this driver as a module, choose M here: the
307 module will be called r8a66597-hcd.
309 config SUPERH_ON_CHIP_R8A66597
310 boolean "Enable SuperH on-chip R8A66597 USB"
311 depends on USB_R8A66597_HCD && (CPU_SUBTYPE_SH7366 || CPU_SUBTYPE_SH7723)
313 This driver enables support for the on-chip R8A66597 in the
314 SH7366 and SH7723 processors.
317 tristate "Wireless USB Host Controller Interface (WHCI) driver (EXPERIMENTAL)"
