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
75 config USB_EHCI_BIG_ENDIAN_DESC
77 depends on USB_EHCI_HCD
80 config USB_ISP116X_HCD
81 tristate "ISP116X HCD support"
84 The ISP1160 and ISP1161 chips are USB host controllers. Enable this
85 option if your board has this chip. If unsure, say N.
87 This driver does not support isochronous transfers.
89 To compile this driver as a module, choose M here: the
90 module will be called isp116x-hcd.
93 tristate "OHCI HCD support"
94 depends on USB && USB_ARCH_HAS_OHCI
95 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3
96 select I2C if ARCH_PNX4008
98 The Open Host Controller Interface (OHCI) is a standard for accessing
99 USB 1.1 host controller hardware. It does more in hardware than Intel's
100 UHCI specification. If your USB host controller follows the OHCI spec,
101 say Y. On most non-x86 systems, and on x86 hardware that's not using a
102 USB controller from Intel or VIA, this is appropriate. If your host
103 controller doesn't use PCI, this is probably appropriate. For a PCI
104 based system where you're not sure, the "lspci -v" entry will list the
105 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
107 To compile this driver as a module, choose M here: the
108 module will be called ohci-hcd.
110 config USB_OHCI_HCD_PPC_SOC
111 bool "OHCI support for on-chip PPC USB controller"
112 depends on USB_OHCI_HCD && (STB03xxx || PPC_MPC52xx)
114 select USB_OHCI_BIG_ENDIAN_DESC
115 select USB_OHCI_BIG_ENDIAN_MMIO
117 Enables support for the USB controller on the MPC52xx or
118 STB03xxx processor chip. If unsure, say Y.
120 config USB_OHCI_HCD_PPC_OF
121 bool "OHCI support for PPC USB controller on OF platform bus"
122 depends on USB_OHCI_HCD && PPC_OF
125 Enables support for the USB controller PowerPC present on the
126 OpenFirmware platform bus.
128 config USB_OHCI_HCD_PPC_OF_BE
129 bool "Support big endian HC"
130 depends on USB_OHCI_HCD_PPC_OF
132 select USB_OHCI_BIG_ENDIAN_DESC
133 select USB_OHCI_BIG_ENDIAN_MMIO
135 config USB_OHCI_HCD_PPC_OF_LE
136 bool "Support little endian HC"
137 depends on USB_OHCI_HCD_PPC_OF
139 select USB_OHCI_LITTLE_ENDIAN
141 config USB_OHCI_HCD_PCI
142 bool "OHCI support for PCI-bus USB controllers"
143 depends on USB_OHCI_HCD && PCI && (STB03xxx || PPC_MPC52xx || USB_OHCI_HCD_PPC_OF)
145 select USB_OHCI_LITTLE_ENDIAN
147 Enables support for PCI-bus plug-in USB controller cards.
150 config USB_OHCI_BIG_ENDIAN_DESC
152 depends on USB_OHCI_HCD
155 config USB_OHCI_BIG_ENDIAN_MMIO
157 depends on USB_OHCI_HCD
160 config USB_OHCI_LITTLE_ENDIAN
162 depends on USB_OHCI_HCD
163 default n if STB03xxx || PPC_MPC52xx
167 tristate "UHCI HCD (most Intel and VIA) support"
168 depends on USB && PCI
170 The Universal Host Controller Interface is a standard by Intel for
171 accessing the USB hardware in the PC (which is also called the USB
172 host controller). If your USB host controller conforms to this
173 standard, you may want to say Y, but see below. All recent boards
174 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
175 i810, i820) conform to this standard. Also all VIA PCI chipsets
176 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
177 133). If unsure, say Y.
179 To compile this driver as a module, choose M here: the
180 module will be called uhci-hcd.
183 tristate "Elan U132 Adapter Host Controller"
184 depends on USB && USB_FTDI_ELAN
187 The U132 adapter is a USB to CardBus adapter specifically designed
188 for PC cards that contain an OHCI host controller. Typical PC cards
189 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
190 adapter will *NOT* work with PC cards that do not contain an OHCI
193 For those PC cards that contain multiple OHCI controllers only the
196 The driver consists of two modules, the "ftdi-elan" module is a
197 USB client driver that interfaces to the FTDI chip within ELAN's
198 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
199 controller driver that talks to the OHCI controller within the
200 CardBus cards that are inserted in the U132 adapter.
202 This driver has been tested with a CardBus OHCI USB adapter, and
203 worked with a USB PEN Drive inserted into the first USB port of
204 the PCCARD. A rather pointless thing to do, but useful for testing.
206 It is safe to say M here.

211 tristate "SL811HS HCD support"
214 The SL811HS is a single-port USB controller that supports either
215 host side or peripheral side roles. Enable this option if your
216 board has this chip, and you want to use it as a host controller.
219 To compile this driver as a module, choose M here: the
220 module will be called sl811-hcd.
223 tristate "CF/PCMCIA support for SL811HS HCD"
224 depends on USB_SL811_HCD && PCMCIA
226 Wraps a PCMCIA driver around the SL811HS HCD, supporting the RATOC
227 REX-CFU1U CF card (often used with PDAs). If unsure, say N.
229 To compile this driver as a module, choose M here: the
230 module will be called "sl811_cs".
232 config USB_R8A66597_HCD
233 tristate "R8A66597 HCD suppoort"
236 The R8A66597 is a USB 2.0 host and peripheral controller.
238 Enable this option if your board has this chip, and you want
239 to use it as a host controller. If unsure, say N.
241 To compile this driver as a module, choose M here: the
242 module will be called r8a66597-hcd.
