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_SPLIT_ISO
33 bool "Full speed ISO transactions (EXPERIMENTAL)"
34 depends on USB_EHCI_HCD && EXPERIMENTAL
37 This code is new and hasn't been used with many different
38 EHCI or USB 2.0 transaction translator implementations.
39 It should work for ISO-OUT transfers, like audio.
41 config USB_EHCI_ROOT_HUB_TT
42 bool "Root Hub Transaction Translators (EXPERIMENTAL)"
43 depends on USB_EHCI_HCD && EXPERIMENTAL
45 Some EHCI chips have vendor-specific extensions to integrate
46 transaction translators, so that no OHCI or UHCI companion
47 controller is needed. It's safe to say "y" even if your
48 controller doesn't support this feature.
50 This supports the EHCI implementation that's originally
51 from ARC, and has since changed hands a few times.
53 config USB_EHCI_TT_NEWSCHED
54 bool "Improved Transaction Translator scheduling (EXPERIMENTAL)"
55 depends on USB_EHCI_HCD && EXPERIMENTAL
57 This changes the periodic scheduling code to fill more of the low
58 and full speed bandwidth available from the Transaction Translator
59 (TT) in USB 2.0 hubs. Without this, only one transfer will be
60 issued in each microframe, significantly reducing the number of
61 periodic low/fullspeed transfers possible.
63 If you have multiple periodic low/fullspeed devices connected to a
64 highspeed USB hub which is connected to a highspeed USB Host
65 Controller, and some of those devices will not work correctly
66 (possibly due to "ENOSPC" or "-28" errors), say Y.
70 config USB_EHCI_BIG_ENDIAN_MMIO
72 depends on USB_EHCI_HCD && (PPC_CELLEB || PPC_PS3 || 440EPX)
75 config USB_EHCI_BIG_ENDIAN_DESC
77 depends on USB_EHCI_HCD && 440EPX
82 depends on USB_EHCI_HCD
83 select USB_EHCI_ROOT_HUB_TT
84 default y if MPC834x || PPC_MPC831x
86 Variation of ARC USB block used in some Freescale chips.
88 config USB_ISP116X_HCD
89 tristate "ISP116X HCD support"
92 The ISP1160 and ISP1161 chips are USB host controllers. Enable this
93 option if your board has this chip. If unsure, say N.
95 This driver does not support isochronous transfers.
97 To compile this driver as a module, choose M here: the
98 module will be called isp116x-hcd.
101 tristate "OHCI HCD support"
102 depends on USB && USB_ARCH_HAS_OHCI
103 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3
104 select I2C if ARCH_PNX4008
106 The Open Host Controller Interface (OHCI) is a standard for accessing
107 USB 1.1 host controller hardware. It does more in hardware than Intel's
108 UHCI specification. If your USB host controller follows the OHCI spec,
109 say Y. On most non-x86 systems, and on x86 hardware that's not using a
110 USB controller from Intel or VIA, this is appropriate. If your host
111 controller doesn't use PCI, this is probably appropriate. For a PCI
112 based system where you're not sure, the "lspci -v" entry will list the
113 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
115 To compile this driver as a module, choose M here: the
116 module will be called ohci-hcd.
118 config USB_OHCI_HCD_PPC_SOC
119 bool "OHCI support for on-chip PPC USB controller"
120 depends on USB_OHCI_HCD && (STB03xxx || PPC_MPC52xx)
122 select USB_OHCI_BIG_ENDIAN_DESC
123 select USB_OHCI_BIG_ENDIAN_MMIO
125 Enables support for the USB controller on the MPC52xx or
126 STB03xxx processor chip. If unsure, say Y.
128 config USB_OHCI_HCD_PPC_OF
129 bool "OHCI support for PPC USB controller on OF platform bus"
130 depends on USB_OHCI_HCD && PPC_OF
133 Enables support for the USB controller PowerPC present on the
134 OpenFirmware platform bus.
136 config USB_OHCI_HCD_PPC_OF_BE
137 bool "Support big endian HC"
138 depends on USB_OHCI_HCD_PPC_OF
140 select USB_OHCI_BIG_ENDIAN_DESC
141 select USB_OHCI_BIG_ENDIAN_MMIO
143 config USB_OHCI_HCD_PPC_OF_LE
144 bool "Support little endian HC"
145 depends on USB_OHCI_HCD_PPC_OF
147 select USB_OHCI_LITTLE_ENDIAN
149 config USB_OHCI_HCD_PCI
150 bool "OHCI support for PCI-bus USB controllers"
151 depends on USB_OHCI_HCD && PCI && (STB03xxx || PPC_MPC52xx || USB_OHCI_HCD_PPC_OF)
153 select USB_OHCI_LITTLE_ENDIAN
155 Enables support for PCI-bus plug-in USB controller cards.
158 config USB_OHCI_HCD_SSB
159 bool "OHCI support for Broadcom SSB OHCI core"
160 depends on USB_OHCI_HCD && (SSB = y || SSB = USB_OHCI_HCD) && EXPERIMENTAL
163 Support for the Sonics Silicon Backplane (SSB) attached
164 Broadcom USB OHCI core.
166 This device is present in some embedded devices with
167 Broadcom based SSB bus.
171 config USB_OHCI_BIG_ENDIAN_DESC
173 depends on USB_OHCI_HCD
176 config USB_OHCI_BIG_ENDIAN_MMIO
178 depends on USB_OHCI_HCD
181 config USB_OHCI_LITTLE_ENDIAN
183 depends on USB_OHCI_HCD
184 default n if STB03xxx || PPC_MPC52xx
188 tristate "UHCI HCD (most Intel and VIA) support"
189 depends on USB && PCI
191 The Universal Host Controller Interface is a standard by Intel for
192 accessing the USB hardware in the PC (which is also called the USB
193 host controller). If your USB host controller conforms to this
194 standard, you may want to say Y, but see below. All recent boards
195 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
196 i810, i820) conform to this standard. Also all VIA PCI chipsets
197 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
198 133). If unsure, say Y.
200 To compile this driver as a module, choose M here: the
201 module will be called uhci-hcd.
204 tristate "Elan U132 Adapter Host Controller"
205 depends on USB && USB_FTDI_ELAN
208 The U132 adapter is a USB to CardBus adapter specifically designed
209 for PC cards that contain an OHCI host controller. Typical PC cards
210 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
211 adapter will *NOT* work with PC cards that do not contain an OHCI
214 For those PC cards that contain multiple OHCI controllers only the
217 The driver consists of two modules, the "ftdi-elan" module is a
218 USB client driver that interfaces to the FTDI chip within ELAN's
219 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
220 controller driver that talks to the OHCI controller within the
221 CardBus cards that are inserted in the U132 adapter.
223 This driver has been tested with a CardBus OHCI USB adapter, and
224 worked with a USB PEN Drive inserted into the first USB port of
225 the PCCARD. A rather pointless thing to do, but useful for testing.
227 It is safe to say M here.

232 tristate "SL811HS HCD support"
235 The SL811HS is a single-port USB controller that supports either
236 host side or peripheral side roles. Enable this option if your
237 board has this chip, and you want to use it as a host controller.
240 To compile this driver as a module, choose M here: the
241 module will be called sl811-hcd.
244 tristate "CF/PCMCIA support for SL811HS HCD"
245 depends on USB_SL811_HCD && PCMCIA
247 Wraps a PCMCIA driver around the SL811HS HCD, supporting the RATOC
248 REX-CFU1U CF card (often used with PDAs). If unsure, say N.
250 To compile this driver as a module, choose M here: the
251 module will be called "sl811_cs".
253 config USB_R8A66597_HCD
254 tristate "R8A66597 HCD support"
257 The R8A66597 is a USB 2.0 host and peripheral controller.
259 Enable this option if your board has this chip, and you want
260 to use it as a host controller. If unsure, say N.
262 To compile this driver as a module, choose M here: the
263 module will be called r8a66597-hcd.
