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.
33 depends on USB_EHCI_HCD && EXPERIMENTAL && ARCH_OMAP34XX
35 Choose PHY or TLL mode of operation
37 config OMAP_EHCI_PHY_MODE
38 bool "PHY mode: ISP1504 on Port1/2 (NEW 3430ES2.0)"
39 depends on USB_EHCI_HCD && EXPERIMENTAL && ARCH_OMAP34XX
41 EHCI PHY mode. Port1 and Port2 are connected to ISP1504 transcievers
43 config OMAP_EHCI_TLL_MODE
44 bool "TLL mode: (EXPERIMENTAL)"
45 depends on USB_EHCI_HCD && EXPERIMENTAL && ARCH_OMAP34XX
47 OMAP EHCI controller has TLL mode of operation for all 3 ports.
48 Use this mode when no transciever is present
51 config USB_EHCI_SPLIT_ISO
52 bool "Full speed ISO transactions (EXPERIMENTAL)"
53 depends on USB_EHCI_HCD && EXPERIMENTAL
56 This code is new and hasn't been used with many different
57 EHCI or USB 2.0 transaction translator implementations.
58 It should work for ISO-OUT transfers, like audio.
60 config USB_EHCI_ROOT_HUB_TT
61 bool "Root Hub Transaction Translators (EXPERIMENTAL)"
62 depends on USB_EHCI_HCD && EXPERIMENTAL
64 Some EHCI chips have vendor-specific extensions to integrate
65 transaction translators, so that no OHCI or UHCI companion
66 controller is needed. It's safe to say "y" even if your
67 controller doesn't support this feature.
69 This supports the EHCI implementation that's originally
70 from ARC, and has since changed hands a few times.
72 config USB_EHCI_TT_NEWSCHED
73 bool "Improved Transaction Translator scheduling (EXPERIMENTAL)"
74 depends on USB_EHCI_HCD && EXPERIMENTAL
76 This changes the periodic scheduling code to fill more of the low
77 and full speed bandwidth available from the Transaction Translator
78 (TT) in USB 2.0 hubs. Without this, only one transfer will be
79 issued in each microframe, significantly reducing the number of
80 periodic low/fullspeed transfers possible.
82 If you have multiple periodic low/fullspeed devices connected to a
83 highspeed USB hub which is connected to a highspeed USB Host
84 Controller, and some of those devices will not work correctly
85 (possibly due to "ENOSPC" or "-28" errors), say Y.
89 config USB_EHCI_BIG_ENDIAN_MMIO
91 depends on USB_EHCI_HCD && (PPC_CELLEB || PPC_PS3 || 440EPX)
94 config USB_EHCI_BIG_ENDIAN_DESC
96 depends on USB_EHCI_HCD && 440EPX
101 select USB_EHCI_ROOT_HUB_TT
102 default y if MPC834x || PPC_MPC831x
104 Variation of ARC USB block used in some Freescale chips.
106 config USB_ISP116X_HCD
107 tristate "ISP116X HCD support"
110 The ISP1160 and ISP1161 chips are USB host controllers. Enable this
111 option if your board has this chip. If unsure, say N.
113 This driver does not support isochronous transfers.
115 To compile this driver as a module, choose M here: the
116 module will be called isp116x-hcd.
119 tristate "OHCI HCD support"
120 depends on USB && USB_ARCH_HAS_OHCI
121 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3
122 select I2C if ARCH_PNX4008
124 The Open Host Controller Interface (OHCI) is a standard for accessing
125 USB 1.1 host controller hardware. It does more in hardware than Intel's
126 UHCI specification. If your USB host controller follows the OHCI spec,
127 say Y. On most non-x86 systems, and on x86 hardware that's not using a
128 USB controller from Intel or VIA, this is appropriate. If your host
129 controller doesn't use PCI, this is probably appropriate. For a PCI
130 based system where you're not sure, the "lspci -v" entry will list the
131 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
133 To compile this driver as a module, choose M here: the
134 module will be called ohci-hcd.
136 config USB_OHCI_HCD_PPC_SOC
137 bool "OHCI support for on-chip PPC USB controller"
138 depends on USB_OHCI_HCD && (STB03xxx || PPC_MPC52xx)
140 select USB_OHCI_BIG_ENDIAN_DESC
141 select USB_OHCI_BIG_ENDIAN_MMIO
143 Enables support for the USB controller on the MPC52xx or
144 STB03xxx processor chip. If unsure, say Y.
146 config USB_OHCI_HCD_PPC_OF
147 bool "OHCI support for PPC USB controller on OF platform bus"
148 depends on USB_OHCI_HCD && PPC_OF
151 Enables support for the USB controller PowerPC present on the
152 OpenFirmware platform bus.
154 config USB_OHCI_HCD_PPC_OF_BE
155 bool "Support big endian HC"
156 depends on USB_OHCI_HCD_PPC_OF
158 select USB_OHCI_BIG_ENDIAN_DESC
159 select USB_OHCI_BIG_ENDIAN_MMIO
161 config USB_OHCI_HCD_PPC_OF_LE
162 bool "Support little endian HC"
163 depends on USB_OHCI_HCD_PPC_OF
165 select USB_OHCI_LITTLE_ENDIAN
167 config USB_OHCI_HCD_PCI
168 bool "OHCI support for PCI-bus USB controllers"
169 depends on USB_OHCI_HCD && PCI && (STB03xxx || PPC_MPC52xx || USB_OHCI_HCD_PPC_OF)
171 select USB_OHCI_LITTLE_ENDIAN
173 Enables support for PCI-bus plug-in USB controller cards.
176 config USB_OHCI_HCD_SSB
177 bool "OHCI support for Broadcom SSB OHCI core"
178 depends on USB_OHCI_HCD && (SSB = y || SSB = USB_OHCI_HCD) && EXPERIMENTAL
181 Support for the Sonics Silicon Backplane (SSB) attached
182 Broadcom USB OHCI core.
184 This device is present in some embedded devices with
185 Broadcom based SSB bus.
189 config USB_OHCI_BIG_ENDIAN_DESC
191 depends on USB_OHCI_HCD
194 config USB_OHCI_BIG_ENDIAN_MMIO
196 depends on USB_OHCI_HCD
199 config USB_OHCI_LITTLE_ENDIAN
201 depends on USB_OHCI_HCD

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

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