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_ISP116X_HCD
100 tristate "ISP116X HCD support"
103 The ISP1160 and ISP1161 chips are USB host controllers. Enable this
104 option if your board has this chip. If unsure, say N.
106 This driver does not support isochronous transfers.
108 To compile this driver as a module, choose M here: the
109 module will be called isp116x-hcd.
111 config USB_ISP1760_HCD
112 tristate "ISP 1760 HCD support"
113 depends on USB && EXPERIMENTAL
115 The ISP1760 chip is a USB 2.0 host controller.
117 This driver does not support isochronous transfers or OTG.
119 To compile this driver as a module, choose M here: the
120 module will be called isp1760-hcd.
122 config USB_ISP1760_PCI
123 bool "Support for the PCI bus"
124 depends on USB_ISP1760_HCD && PCI
126 Enables support for the device present on the PCI bus.
127 This should only be required if you happen to have the eval kit from
128 NXP and you are going to test it.
130 config USB_ISP1760_OF
131 bool "Support for the OF platform bus"
132 depends on USB_ISP1760_HCD && PPC_OF
134 Enables support for the device present on the PowerPC
135 OpenFirmware platform bus.
138 tristate "OHCI HCD support"
139 depends on USB && USB_ARCH_HAS_OHCI
140 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3
141 select I2C if ARCH_PNX4008
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.
152 To compile this driver as a module, choose M here: the
153 module will be called ohci-hcd.
155 config USB_OHCI_HCD_PPC_SOC
156 bool "OHCI support for on-chip PPC USB controller"
157 depends on USB_OHCI_HCD && (STB03xxx || PPC_MPC52xx)
159 select USB_OHCI_BIG_ENDIAN_DESC
160 select USB_OHCI_BIG_ENDIAN_MMIO
162 Enables support for the USB controller on the MPC52xx or
163 STB03xxx processor chip. If unsure, say Y.
165 config USB_OHCI_HCD_PPC_OF
166 bool "OHCI support for PPC USB controller on OF platform bus"
167 depends on USB_OHCI_HCD && PPC_OF
170 Enables support for the USB controller PowerPC present on the
171 OpenFirmware platform bus.
173 config USB_OHCI_HCD_PPC_OF_BE
174 bool "Support big endian HC"
175 depends on USB_OHCI_HCD_PPC_OF
177 select USB_OHCI_BIG_ENDIAN_DESC
178 select USB_OHCI_BIG_ENDIAN_MMIO
180 config USB_OHCI_HCD_PPC_OF_LE
181 bool "Support little endian HC"
182 depends on USB_OHCI_HCD_PPC_OF
184 select USB_OHCI_LITTLE_ENDIAN
186 config USB_OHCI_HCD_PCI
187 bool "OHCI support for PCI-bus USB controllers"
188 depends on USB_OHCI_HCD && PCI && (STB03xxx || PPC_MPC52xx || USB_OHCI_HCD_PPC_OF)
190 select USB_OHCI_LITTLE_ENDIAN
192 Enables support for PCI-bus plug-in USB controller cards.
195 config USB_OHCI_HCD_SSB

197 depends on USB_OHCI_HCD && (SSB = y || SSB = USB_OHCI_HCD) && EXPERIMENTAL
200 Support for the Sonics Silicon Backplane (SSB) attached
201 Broadcom USB OHCI core.
203 This device is present in some embedded devices with
204 Broadcom based SSB bus.
208 config USB_OHCI_BIG_ENDIAN_DESC
210 depends on USB_OHCI_HCD
213 config USB_OHCI_BIG_ENDIAN_MMIO
215 depends on USB_OHCI_HCD

220 depends on USB_OHCI_HCD
221 default n if STB03xxx || PPC_MPC52xx
225 tristate "UHCI HCD (most Intel and VIA) support"
226 depends on USB && PCI
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.
237 To compile this driver as a module, choose M here: the
238 module will be called uhci-hcd.
241 tristate "Elan U132 Adapter Host Controller"
242 depends on USB && USB_FTDI_ELAN
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
251 For those PC cards that contain multiple OHCI controllers only the
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.
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.
264 It is safe to say M here.

269 tristate "SL811HS HCD support"
272 The SL811HS is a single-port USB controller that supports either
273 host side or peripheral side roles. Enable this option if your
274 board has this chip, and you want to use it as a host controller.
277 To compile this driver as a module, choose M here: the
278 module will be called sl811-hcd.
281 tristate "CF/PCMCIA support for SL811HS HCD"
282 depends on USB_SL811_HCD && PCMCIA
284 Wraps a PCMCIA driver around the SL811HS HCD, supporting the RATOC
285 REX-CFU1U CF card (often used with PDAs). If unsure, say N.

291 tristate "R8A66597 HCD support"
294 The R8A66597 is a USB 2.0 host and peripheral controller.
296 Enable this option if your board has this chip, and you want
297 to use it as a host controller. If unsure, say N.
299 To compile this driver as a module, choose M here: the
300 module will be called r8a66597-hcd.
302 config SUPERH_ON_CHIP_R8A66597
303 boolean "Enable SuperH on-chip R8A66597 USB"
304 depends on USB_R8A66597_HCD && (CPU_SUBTYPE_SH7366 || CPU_SUBTYPE_SH7723)
306 This driver enables support for the on-chip R8A66597 in the
307 SH7366 and SH7723 processors.
