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 select USB_EHCI_ROOT_HUB_TT
83 default y if MPC834x || PPC_MPC831x
85 Variation of ARC USB block used in some Freescale chips.
87 config USB_ISP116X_HCD
88 tristate "ISP116X HCD support"
91 The ISP1160 and ISP1161 chips are USB host controllers. Enable this
92 option if your board has this chip. If unsure, say N.
94 This driver does not support isochronous transfers.
96 To compile this driver as a module, choose M here: the
97 module will be called isp116x-hcd.
100 tristate "OHCI HCD support"
101 depends on USB && USB_ARCH_HAS_OHCI
102 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3
103 select I2C if ARCH_PNX4008
105 The Open Host Controller Interface (OHCI) is a standard for accessing
106 USB 1.1 host controller hardware. It does more in hardware than Intel's
107 UHCI specification. If your USB host controller follows the OHCI spec,
108 say Y. On most non-x86 systems, and on x86 hardware that's not using a
109 USB controller from Intel or VIA, this is appropriate. If your host
110 controller doesn't use PCI, this is probably appropriate. For a PCI
111 based system where you're not sure, the "lspci -v" entry will list the
112 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
114 To compile this driver as a module, choose M here: the
115 module will be called ohci-hcd.
117 config USB_OHCI_HCD_PPC_SOC
118 bool "OHCI support for on-chip PPC USB controller"
119 depends on USB_OHCI_HCD && (STB03xxx || PPC_MPC52xx)
121 select USB_OHCI_BIG_ENDIAN_DESC
122 select USB_OHCI_BIG_ENDIAN_MMIO
124 Enables support for the USB controller on the MPC52xx or
125 STB03xxx processor chip. If unsure, say Y.
127 config USB_OHCI_HCD_PPC_OF
128 bool "OHCI support for PPC USB controller on OF platform bus"
129 depends on USB_OHCI_HCD && PPC_OF
132 Enables support for the USB controller PowerPC present on the
133 OpenFirmware platform bus.
135 config USB_OHCI_HCD_PPC_OF_BE
136 bool "Support big endian HC"
137 depends on USB_OHCI_HCD_PPC_OF
139 select USB_OHCI_BIG_ENDIAN_DESC
140 select USB_OHCI_BIG_ENDIAN_MMIO
142 config USB_OHCI_HCD_PPC_OF_LE
143 bool "Support little endian HC"
144 depends on USB_OHCI_HCD_PPC_OF
146 select USB_OHCI_LITTLE_ENDIAN
148 config USB_OHCI_HCD_PCI
149 bool "OHCI support for PCI-bus USB controllers"
150 depends on USB_OHCI_HCD && PCI && (STB03xxx || PPC_MPC52xx || USB_OHCI_HCD_PPC_OF)
152 select USB_OHCI_LITTLE_ENDIAN
154 Enables support for PCI-bus plug-in USB controller cards.
157 config USB_OHCI_BIG_ENDIAN_DESC
159 depends on USB_OHCI_HCD
162 config USB_OHCI_BIG_ENDIAN_MMIO
164 depends on USB_OHCI_HCD
167 config USB_OHCI_LITTLE_ENDIAN
169 depends on USB_OHCI_HCD
170 default n if STB03xxx || PPC_MPC52xx
174 tristate "UHCI HCD (most Intel and VIA) support"
175 depends on USB && PCI
177 The Universal Host Controller Interface is a standard by Intel for
178 accessing the USB hardware in the PC (which is also called the USB
179 host controller). If your USB host controller conforms to this
180 standard, you may want to say Y, but see below. All recent boards
181 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
182 i810, i820) conform to this standard. Also all VIA PCI chipsets
183 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
184 133). If unsure, say Y.
186 To compile this driver as a module, choose M here: the
187 module will be called uhci-hcd.
190 tristate "Elan U132 Adapter Host Controller"
191 depends on USB && USB_FTDI_ELAN
194 The U132 adapter is a USB to CardBus adapter specifically designed
195 for PC cards that contain an OHCI host controller. Typical PC cards
196 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
197 adapter will *NOT* work with PC cards that do not contain an OHCI
200 For those PC cards that contain multiple OHCI controllers only the
203 The driver consists of two modules, the "ftdi-elan" module is a
204 USB client driver that interfaces to the FTDI chip within ELAN's
205 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
206 controller driver that talks to the OHCI controller within the
207 CardBus cards that are inserted in the U132 adapter.
209 This driver has been tested with a CardBus OHCI USB adapter, and
210 worked with a USB PEN Drive inserted into the first USB port of
211 the PCCARD. A rather pointless thing to do, but useful for testing.
213 It is safe to say M here.

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