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.
45 config USB_EHCI_ROOT_HUB_TT
46 bool "Root Hub Transaction Translators"
47 depends on USB_EHCI_HCD
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.
54 This supports the EHCI implementation that's originally
55 from ARC, and has since changed hands a few times.
57 config USB_EHCI_TT_NEWSCHED
58 bool "Improved Transaction Translator scheduling (EXPERIMENTAL)"
59 depends on USB_EHCI_HCD && EXPERIMENTAL
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.
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.
74 config USB_EHCI_BIG_ENDIAN_MMIO
76 depends on USB_EHCI_HCD && (PPC_CELLEB || PPC_PS3 || 440EPX || ARCH_IXP4XX)
79 config USB_EHCI_BIG_ENDIAN_DESC
81 depends on USB_EHCI_HCD && (440EPX || ARCH_IXP4XX)
85 bool "Support for Freescale on-chip EHCI USB controller"
86 depends on USB_EHCI_HCD && FSL_SOC
87 select USB_EHCI_ROOT_HUB_TT
89 Variation of ARC USB block used in some Freescale chips.
91 config USB_EHCI_HCD_PPC_OF
92 bool "EHCI support for PPC USB controller on OF platform bus"
93 depends on USB_EHCI_HCD && PPC_OF
96 Enables support for the USB controller present on the PowerPC
97 OpenFirmware platform bus.
99 config USB_OXU210HP_HCD
100 tristate "OXU210HP HCD support"
103 The OXU210HP is an USB host/OTG/device controller. Enable this
104 option if your board has this chip. If unsure, say N.
106 This driver does not support isochronous transfers and doesn't
107 implement OTG nor USB device controllers.
109 To compile this driver as a module, choose M here: the
110 module will be called oxu210hp-hcd.
112 config USB_ISP116X_HCD
113 tristate "ISP116X HCD support"
116 The ISP1160 and ISP1161 chips are USB host controllers. Enable this
117 option if your board has this chip. If unsure, say N.
119 This driver does not support isochronous transfers.
121 To compile this driver as a module, choose M here: the
122 module will be called isp116x-hcd.
124 config USB_ISP1760_HCD
125 tristate "ISP 1760 HCD support"
126 depends on USB && EXPERIMENTAL && (PCI || PPC_OF)
128 The ISP1760 chip is a USB 2.0 host controller.
130 This driver does not support isochronous transfers or OTG.
131 This USB controller is usually attached to a non-DMA-Master
132 capable bus. NXP's eval kit brings this chip on PCI card
133 where the chip itself is behind a PLB to simulate such
136 To compile this driver as a module, choose M here: the
137 module will be called isp1760.
140 tristate "OHCI HCD support"
141 depends on USB && USB_ARCH_HAS_OHCI
142 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3
143 select USB_OTG_UTILS if ARCH_OMAP
145 The Open Host Controller Interface (OHCI) is a standard for accessing
146 USB 1.1 host controller hardware. It does more in hardware than Intel's
147 UHCI specification. If your USB host controller follows the OHCI spec,
148 say Y. On most non-x86 systems, and on x86 hardware that's not using a
149 USB controller from Intel or VIA, this is appropriate. If your host
150 controller doesn't use PCI, this is probably appropriate. For a PCI
151 based system where you're not sure, the "lspci -v" entry will list the
152 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
154 To compile this driver as a module, choose M here: the
155 module will be called ohci-hcd.
157 config USB_OHCI_HCD_PPC_SOC
158 bool "OHCI support for on-chip PPC USB controller"

161 select USB_OHCI_BIG_ENDIAN_DESC
162 select USB_OHCI_BIG_ENDIAN_MMIO
164 Enables support for the USB controller on the MPC52xx or
165 STB03xxx processor chip. If unsure, say Y.
167 config USB_OHCI_HCD_PPC_OF
168 bool "OHCI support for PPC USB controller on OF platform bus"
169 depends on USB_OHCI_HCD && PPC_OF
172 Enables support for the USB controller PowerPC present on the
173 OpenFirmware platform bus.
175 config USB_OHCI_HCD_PPC_OF_BE
176 bool "Support big endian HC"
177 depends on USB_OHCI_HCD_PPC_OF
179 select USB_OHCI_BIG_ENDIAN_DESC
180 select USB_OHCI_BIG_ENDIAN_MMIO
182 config USB_OHCI_HCD_PPC_OF_LE
183 bool "Support little endian HC"

186 select USB_OHCI_LITTLE_ENDIAN
188 config USB_OHCI_HCD_PCI
189 bool "OHCI support for PCI-bus USB controllers"
190 depends on USB_OHCI_HCD && PCI && (STB03xxx || PPC_MPC52xx || USB_OHCI_HCD_PPC_OF)
192 select USB_OHCI_LITTLE_ENDIAN
194 Enables support for PCI-bus plug-in USB controller cards.
197 config USB_OHCI_HCD_SSB
198 bool "OHCI support for Broadcom SSB OHCI core"
199 depends on USB_OHCI_HCD && (SSB = y || SSB = USB_OHCI_HCD) && EXPERIMENTAL
202 Support for the Sonics Silicon Backplane (SSB) attached
203 Broadcom USB OHCI core.
205 This device is present in some embedded devices with
206 Broadcom based SSB bus.
210 config USB_OHCI_BIG_ENDIAN_DESC
212 depends on USB_OHCI_HCD
215 config USB_OHCI_BIG_ENDIAN_MMIO

222 depends on USB_OHCI_HCD
223 default n if STB03xxx || PPC_MPC52xx
227 tristate "UHCI HCD (most Intel and VIA) support"
228 depends on USB && PCI
230 The Universal Host Controller Interface is a standard by Intel for
231 accessing the USB hardware in the PC (which is also called the USB
232 host controller). If your USB host controller conforms to this
233 standard, you may want to say Y, but see below. All recent boards
234 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
235 i810, i820) conform to this standard. Also all VIA PCI chipsets
236 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
237 133). If unsure, say Y.
239 To compile this driver as a module, choose M here: the
240 module will be called uhci-hcd.
243 tristate "Freescale QE USB Host Controller support"

250 Full and Low Speed USB.
253 bool "Freescale QE USB Host Controller debug support"
254 depends on USB_FHCI_HCD && DEBUG_FS
256 Say "y" to see some FHCI debug information and statistics
260 tristate "Elan U132 Adapter Host Controller"
261 depends on USB && USB_FTDI_ELAN
264 The U132 adapter is a USB to CardBus adapter specifically designed
265 for PC cards that contain an OHCI host controller. Typical PC cards
266 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
267 adapter will *NOT* work with PC cards that do not contain an OHCI
270 For those PC cards that contain multiple OHCI controllers only the
273 The driver consists of two modules, the "ftdi-elan" module is a
274 USB client driver that interfaces to the FTDI chip within ELAN's
275 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
276 controller driver that talks to the OHCI controller within the
277 CardBus cards that are inserted in the U132 adapter.
279 This driver has been tested with a CardBus OHCI USB adapter, and
280 worked with a USB PEN Drive inserted into the first USB port of
281 the PCCARD. A rather pointless thing to do, but useful for testing.
283 It is safe to say M here.
