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 || ARCH_IXP4XX)
75 config USB_EHCI_BIG_ENDIAN_DESC
77 depends on USB_EHCI_HCD && (440EPX || ARCH_IXP4XX)
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_EHCI_HCD_PPC_OF
89 bool "EHCI support for PPC USB controller on OF platform bus"
90 depends on USB_EHCI_HCD && PPC_OF
93 Enables support for the USB controller present on the PowerPC
94 OpenFirmware platform bus.
96 config USB_ISP116X_HCD
97 tristate "ISP116X HCD support"
100 The ISP1160 and ISP1161 chips are USB host controllers. Enable this
101 option if your board has this chip. If unsure, say N.
103 This driver does not support isochronous transfers.
105 To compile this driver as a module, choose M here: the
106 module will be called isp116x-hcd.
109 tristate "OHCI HCD support"
110 depends on USB && USB_ARCH_HAS_OHCI
111 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3
112 select I2C if ARCH_PNX4008
114 The Open Host Controller Interface (OHCI) is a standard for accessing
115 USB 1.1 host controller hardware. It does more in hardware than Intel's
116 UHCI specification. If your USB host controller follows the OHCI spec,
117 say Y. On most non-x86 systems, and on x86 hardware that's not using a
118 USB controller from Intel or VIA, this is appropriate. If your host
119 controller doesn't use PCI, this is probably appropriate. For a PCI
120 based system where you're not sure, the "lspci -v" entry will list the
121 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
123 To compile this driver as a module, choose M here: the
124 module will be called ohci-hcd.
126 config USB_OHCI_HCD_PPC_SOC
127 bool "OHCI support for on-chip PPC USB controller"
128 depends on USB_OHCI_HCD && (STB03xxx || PPC_MPC52xx)
130 select USB_OHCI_BIG_ENDIAN_DESC
131 select USB_OHCI_BIG_ENDIAN_MMIO
133 Enables support for the USB controller on the MPC52xx or
134 STB03xxx processor chip. If unsure, say Y.
136 config USB_OHCI_HCD_PPC_OF
137 bool "OHCI support for PPC USB controller on OF platform bus"
138 depends on USB_OHCI_HCD && PPC_OF
141 Enables support for the USB controller PowerPC present on the
142 OpenFirmware platform bus.
144 config USB_OHCI_HCD_PPC_OF_BE
145 bool "Support big endian HC"
146 depends on USB_OHCI_HCD_PPC_OF
148 select USB_OHCI_BIG_ENDIAN_DESC
149 select USB_OHCI_BIG_ENDIAN_MMIO
151 config USB_OHCI_HCD_PPC_OF_LE
152 bool "Support little endian HC"
153 depends on USB_OHCI_HCD_PPC_OF
155 select USB_OHCI_LITTLE_ENDIAN
157 config USB_OHCI_HCD_PCI
158 bool "OHCI support for PCI-bus USB controllers"
159 depends on USB_OHCI_HCD && PCI && (STB03xxx || PPC_MPC52xx || USB_OHCI_HCD_PPC_OF)
161 select USB_OHCI_LITTLE_ENDIAN
163 Enables support for PCI-bus plug-in USB controller cards.
166 config USB_OHCI_HCD_SSB
167 bool "OHCI support for Broadcom SSB OHCI core"
168 depends on USB_OHCI_HCD && (SSB = y || SSB = USB_OHCI_HCD) && EXPERIMENTAL
171 Support for the Sonics Silicon Backplane (SSB) attached
172 Broadcom USB OHCI core.
174 This device is present in some embedded devices with
175 Broadcom based SSB bus.
179 config USB_OHCI_BIG_ENDIAN_DESC
181 depends on USB_OHCI_HCD
184 config USB_OHCI_BIG_ENDIAN_MMIO
186 depends on USB_OHCI_HCD
189 config USB_OHCI_LITTLE_ENDIAN
191 depends on USB_OHCI_HCD
192 default n if STB03xxx || PPC_MPC52xx
196 tristate "UHCI HCD (most Intel and VIA) support"
197 depends on USB && PCI
199 The Universal Host Controller Interface is a standard by Intel for
200 accessing the USB hardware in the PC (which is also called the USB
201 host controller). If your USB host controller conforms to this
202 standard, you may want to say Y, but see below. All recent boards
203 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
204 i810, i820) conform to this standard. Also all VIA PCI chipsets
205 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
206 133). If unsure, say Y.
208 To compile this driver as a module, choose M here: the
209 module will be called uhci-hcd.
212 tristate "Elan U132 Adapter Host Controller"
213 depends on USB && USB_FTDI_ELAN
216 The U132 adapter is a USB to CardBus adapter specifically designed
217 for PC cards that contain an OHCI host controller. Typical PC cards
218 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
219 adapter will *NOT* work with PC cards that do not contain an OHCI
222 For those PC cards that contain multiple OHCI controllers only the
225 The driver consists of two modules, the "ftdi-elan" module is a
226 USB client driver that interfaces to the FTDI chip within ELAN's
227 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
228 controller driver that talks to the OHCI controller within the
229 CardBus cards that are inserted in the U132 adapter.
231 This driver has been tested with a CardBus OHCI USB adapter, and
232 worked with a USB PEN Drive inserted into the first USB port of
233 the PCCARD. A rather pointless thing to do, but useful for testing.
235 It is safe to say M here.

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