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 && (PCI || PPC_OF)
115 The ISP1760 chip is a USB 2.0 host controller.
117 This driver does not support isochronous transfers or OTG.
118 This USB controller is usually attached to a non-DMA-Master
119 capable bus. NXP's eval kit brings this chip on PCI card
120 where the chip itself is behind a PLB to simulate such
123 To compile this driver as a module, choose M here: the
124 module will be called isp1760.
127 tristate "OHCI HCD support"
128 depends on USB && USB_ARCH_HAS_OHCI
129 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3
131 The Open Host Controller Interface (OHCI) is a standard for accessing
132 USB 1.1 host controller hardware. It does more in hardware than Intel's
133 UHCI specification. If your USB host controller follows the OHCI spec,
134 say Y. On most non-x86 systems, and on x86 hardware that's not using a
135 USB controller from Intel or VIA, this is appropriate. If your host
136 controller doesn't use PCI, this is probably appropriate. For a PCI
137 based system where you're not sure, the "lspci -v" entry will list the
138 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
140 To compile this driver as a module, choose M here: the
141 module will be called ohci-hcd.
143 config USB_OHCI_HCD_PPC_SOC
144 bool "OHCI support for on-chip PPC USB controller"
145 depends on USB_OHCI_HCD && (STB03xxx || PPC_MPC52xx)
147 select USB_OHCI_BIG_ENDIAN_DESC
148 select USB_OHCI_BIG_ENDIAN_MMIO
150 Enables support for the USB controller on the MPC52xx or
151 STB03xxx processor chip. If unsure, say Y.
153 config USB_OHCI_HCD_PPC_OF
154 bool "OHCI support for PPC USB controller on OF platform bus"
155 depends on USB_OHCI_HCD && PPC_OF
158 Enables support for the USB controller PowerPC present on the
159 OpenFirmware platform bus.
161 config USB_OHCI_HCD_PPC_OF_BE
162 bool "Support big endian HC"
163 depends on USB_OHCI_HCD_PPC_OF
165 select USB_OHCI_BIG_ENDIAN_DESC
166 select USB_OHCI_BIG_ENDIAN_MMIO
168 config USB_OHCI_HCD_PPC_OF_LE
169 bool "Support little endian HC"
170 depends on USB_OHCI_HCD_PPC_OF
172 select USB_OHCI_LITTLE_ENDIAN
174 config USB_OHCI_HCD_PCI
175 bool "OHCI support for PCI-bus USB controllers"
176 depends on USB_OHCI_HCD && PCI && (STB03xxx || PPC_MPC52xx || USB_OHCI_HCD_PPC_OF)
178 select USB_OHCI_LITTLE_ENDIAN
180 Enables support for PCI-bus plug-in USB controller cards.
183 config USB_OHCI_HCD_SSB
184 bool "OHCI support for Broadcom SSB OHCI core"
185 depends on USB_OHCI_HCD && (SSB = y || SSB = USB_OHCI_HCD) && EXPERIMENTAL
188 Support for the Sonics Silicon Backplane (SSB) attached
189 Broadcom USB OHCI core.
191 This device is present in some embedded devices with
192 Broadcom based SSB bus.
196 config USB_OHCI_BIG_ENDIAN_DESC
198 depends on USB_OHCI_HCD
201 config USB_OHCI_BIG_ENDIAN_MMIO
203 depends on USB_OHCI_HCD
206 config USB_OHCI_LITTLE_ENDIAN
208 depends on USB_OHCI_HCD
209 default n if STB03xxx || PPC_MPC52xx
213 tristate "UHCI HCD (most Intel and VIA) support"
214 depends on USB && PCI
216 The Universal Host Controller Interface is a standard by Intel for
217 accessing the USB hardware in the PC (which is also called the USB
218 host controller). If your USB host controller conforms to this
219 standard, you may want to say Y, but see below. All recent boards
220 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
221 i810, i820) conform to this standard. Also all VIA PCI chipsets
222 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
223 133). If unsure, say Y.
225 To compile this driver as a module, choose M here: the
226 module will be called uhci-hcd.
229 tristate "Elan U132 Adapter Host Controller"
230 depends on USB && USB_FTDI_ELAN
233 The U132 adapter is a USB to CardBus adapter specifically designed
234 for PC cards that contain an OHCI host controller. Typical PC cards
235 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
236 adapter will *NOT* work with PC cards that do not contain an OHCI
239 For those PC cards that contain multiple OHCI controllers only the
242 The driver consists of two modules, the "ftdi-elan" module is a
243 USB client driver that interfaces to the FTDI chip within ELAN's
244 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
245 controller driver that talks to the OHCI controller within the
246 CardBus cards that are inserted in the U132 adapter.
248 This driver has been tested with a CardBus OHCI USB adapter, and
249 worked with a USB PEN Drive inserted into the first USB port of
250 the PCCARD. A rather pointless thing to do, but useful for testing.
252 It is safe to say M here.

257 tristate "SL811HS HCD support"
260 The SL811HS is a single-port USB controller that supports either
261 host side or peripheral side roles. Enable this option if your
262 board has this chip, and you want to use it as a host controller.
265 To compile this driver as a module, choose M here: the
266 module will be called sl811-hcd.
269 tristate "CF/PCMCIA support for SL811HS HCD"
270 depends on USB_SL811_HCD && PCMCIA
272 Wraps a PCMCIA driver around the SL811HS HCD, supporting the RATOC
273 REX-CFU1U CF card (often used with PDAs). If unsure, say N.
275 To compile this driver as a module, choose M here: the
276 module will be called "sl811_cs".
278 config USB_R8A66597_HCD
279 tristate "R8A66597 HCD support"
282 The R8A66597 is a USB 2.0 host and peripheral controller.
284 Enable this option if your board has this chip, and you want
285 to use it as a host controller. If unsure, say N.
287 To compile this driver as a module, choose M here: the
288 module will be called r8a66597-hcd.
290 config SUPERH_ON_CHIP_R8A66597
291 boolean "Enable SuperH on-chip R8A66597 USB"
292 depends on USB_R8A66597_HCD && (CPU_SUBTYPE_SH7366 || CPU_SUBTYPE_SH7723)
294 This driver enables support for the on-chip R8A66597 in the
295 SH7366 and SH7723 processors.
