8 tristate "EHCI HCD (USB 2.0) support"
9 depends on USB && USB_ARCH_HAS_EHCI
11 The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
12 "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
13 If your USB host controller supports USB 2.0, you will likely want to
14 configure this Host Controller Driver. At the time of this writing,
15 the primary implementation of EHCI is a chip from NEC, widely available
16 in add-on PCI cards, but implementations are in the works from other
17 vendors including Intel and Philips. Motherboard support is appearing.
19 EHCI controllers are packaged with "companion" host controllers (OHCI
20 or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
21 will connect to EHCI if the device is high speed, otherwise they
22 connect to a companion controller. If you configure EHCI, you should
23 probably configure the OHCI (for NEC and some other vendors) USB Host
24 Controller Driver or UHCI (for Via motherboards) Host Controller
27 You may want to read <file:Documentation/usb/ehci.txt>.
29 To compile this driver as a module, choose M here: the
30 module will be called ehci-hcd.
32 config USB_EHCI_ROOT_HUB_TT
33 bool "Root Hub Transaction Translators (EXPERIMENTAL)"
34 depends on USB_EHCI_HCD && EXPERIMENTAL
36 Some EHCI chips have vendor-specific extensions to integrate
37 transaction translators, so that no OHCI or UHCI companion
38 controller is needed. It's safe to say "y" even if your
39 controller doesn't support this feature.
41 This supports the EHCI implementation that's originally
42 from ARC, and has since changed hands a few times.
44 config USB_EHCI_TT_NEWSCHED
45 bool "Improved Transaction Translator scheduling (EXPERIMENTAL)"
46 depends on USB_EHCI_HCD && EXPERIMENTAL
48 This changes the periodic scheduling code to fill more of the low
49 and full speed bandwidth available from the Transaction Translator
50 (TT) in USB 2.0 hubs. Without this, only one transfer will be
51 issued in each microframe, significantly reducing the number of
52 periodic low/fullspeed transfers possible.
54 If you have multiple periodic low/fullspeed devices connected to a
55 highspeed USB hub which is connected to a highspeed USB Host
56 Controller, and some of those devices will not work correctly
57 (possibly due to "ENOSPC" or "-28" errors), say Y.
61 config USB_EHCI_BIG_ENDIAN_MMIO
63 depends on USB_EHCI_HCD && (PPC_CELLEB || PPC_PS3 || 440EPX || ARCH_IXP4XX)
66 config USB_EHCI_BIG_ENDIAN_DESC
68 depends on USB_EHCI_HCD && (440EPX || ARCH_IXP4XX)
72 bool "Support for Freescale on-chip EHCI USB controller"
73 depends on USB_EHCI_HCD && FSL_SOC
74 select USB_EHCI_ROOT_HUB_TT
76 Variation of ARC USB block used in some Freescale chips.
78 config USB_EHCI_HCD_PPC_OF
79 bool "EHCI support for PPC USB controller on OF platform bus"
80 depends on USB_EHCI_HCD && PPC_OF
83 Enables support for the USB controller present on the PowerPC
84 OpenFirmware platform bus.
86 config USB_ISP116X_HCD
87 tristate "ISP116X HCD support"
90 The ISP1160 and ISP1161 chips are USB host controllers. Enable this
91 option if your board has this chip. If unsure, say N.
93 This driver does not support isochronous transfers.
95 To compile this driver as a module, choose M here: the
96 module will be called isp116x-hcd.
99 tristate "OHCI HCD support"
100 depends on USB && USB_ARCH_HAS_OHCI
101 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3
102 select I2C if ARCH_PNX4008
104 The Open Host Controller Interface (OHCI) is a standard for accessing
105 USB 1.1 host controller hardware. It does more in hardware than Intel's
106 UHCI specification. If your USB host controller follows the OHCI spec,
107 say Y. On most non-x86 systems, and on x86 hardware that's not using a
108 USB controller from Intel or VIA, this is appropriate. If your host
109 controller doesn't use PCI, this is probably appropriate. For a PCI
110 based system where you're not sure, the "lspci -v" entry will list the
111 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
113 To compile this driver as a module, choose M here: the
114 module will be called ohci-hcd.
116 config USB_OHCI_HCD_PPC_SOC
117 bool "OHCI support for on-chip PPC USB controller"
118 depends on USB_OHCI_HCD && (STB03xxx || PPC_MPC52xx)
120 select USB_OHCI_BIG_ENDIAN_DESC
121 select USB_OHCI_BIG_ENDIAN_MMIO
123 Enables support for the USB controller on the MPC52xx or
124 STB03xxx processor chip. If unsure, say Y.
126 config USB_OHCI_HCD_PPC_OF
127 bool "OHCI support for PPC USB controller on OF platform bus"
128 depends on USB_OHCI_HCD && PPC_OF
131 Enables support for the USB controller PowerPC present on the
132 OpenFirmware platform bus.
134 config USB_OHCI_HCD_PPC_OF_BE
135 bool "Support big endian HC"
136 depends on USB_OHCI_HCD_PPC_OF
138 select USB_OHCI_BIG_ENDIAN_DESC
139 select USB_OHCI_BIG_ENDIAN_MMIO
141 config USB_OHCI_HCD_PPC_OF_LE
142 bool "Support little endian HC"
143 depends on USB_OHCI_HCD_PPC_OF
145 select USB_OHCI_LITTLE_ENDIAN
147 config USB_OHCI_HCD_PCI
148 bool "OHCI support for PCI-bus USB controllers"
149 depends on USB_OHCI_HCD && PCI && (STB03xxx || PPC_MPC52xx || USB_OHCI_HCD_PPC_OF)
151 select USB_OHCI_LITTLE_ENDIAN
153 Enables support for PCI-bus plug-in USB controller cards.
156 config USB_OHCI_HCD_SSB
157 bool "OHCI support for Broadcom SSB OHCI core"
158 depends on USB_OHCI_HCD && (SSB = y || SSB = USB_OHCI_HCD) && EXPERIMENTAL
161 Support for the Sonics Silicon Backplane (SSB) attached
162 Broadcom USB OHCI core.
164 This device is present in some embedded devices with
165 Broadcom based SSB bus.
169 config USB_OHCI_BIG_ENDIAN_DESC
171 depends on USB_OHCI_HCD
174 config USB_OHCI_BIG_ENDIAN_MMIO
176 depends on USB_OHCI_HCD
179 config USB_OHCI_LITTLE_ENDIAN

186 tristate "UHCI HCD (most Intel and VIA) support"
187 depends on USB && PCI
189 The Universal Host Controller Interface is a standard by Intel for
190 accessing the USB hardware in the PC (which is also called the USB
191 host controller). If your USB host controller conforms to this
192 standard, you may want to say Y, but see below. All recent boards
193 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
194 i810, i820) conform to this standard. Also all VIA PCI chipsets
195 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
196 133). If unsure, say Y.
198 To compile this driver as a module, choose M here: the
199 module will be called uhci-hcd.
202 tristate "Elan U132 Adapter Host Controller"
203 depends on USB && USB_FTDI_ELAN
206 The U132 adapter is a USB to CardBus adapter specifically designed
207 for PC cards that contain an OHCI host controller. Typical PC cards
208 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
209 adapter will *NOT* work with PC cards that do not contain an OHCI
212 For those PC cards that contain multiple OHCI controllers only the
215 The driver consists of two modules, the "ftdi-elan" module is a
216 USB client driver that interfaces to the FTDI chip within ELAN's
217 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
218 controller driver that talks to the OHCI controller within the
219 CardBus cards that are inserted in the U132 adapter.
221 This driver has been tested with a CardBus OHCI USB adapter, and
222 worked with a USB PEN Drive inserted into the first USB port of
223 the PCCARD. A rather pointless thing to do, but useful for testing.
225 It is safe to say M here.

230 tristate "SL811HS HCD support"
233 The SL811HS is a single-port USB controller that supports either
234 host side or peripheral side roles. Enable this option if your
235 board has this chip, and you want to use it as a host controller.
238 To compile this driver as a module, choose M here: the
239 module will be called sl811-hcd.
242 tristate "CF/PCMCIA support for SL811HS HCD"
243 depends on USB_SL811_HCD && PCMCIA
245 Wraps a PCMCIA driver around the SL811HS HCD, supporting the RATOC
246 REX-CFU1U CF card (often used with PDAs). If unsure, say N.
248 To compile this driver as a module, choose M here: the
249 module will be called "sl811_cs".
251 config USB_R8A66597_HCD
252 tristate "R8A66597 HCD support"
255 The R8A66597 is a USB 2.0 host and peripheral controller.
257 Enable this option if your board has this chip, and you want
258 to use it as a host controller. If unsure, say N.
260 To compile this driver as a module, choose M here: the
261 module will be called r8a66597-hcd.
