101 tristate "EHCI HCD (USB 2.0) support"
102 depends on HAS_DMA && HAS_IOMEM
104 The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
105 "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
106 If your USB host controller supports USB 2.0, you will likely want to
107 configure this Host Controller Driver.
109 EHCI controllers are packaged with "companion" host controllers (OHCI
110 or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
111 will connect to EHCI if the device is high speed, otherwise they
112 connect to a companion controller. If you configure EHCI, you should
113 probably configure the OHCI (for NEC and some other vendors) USB Host
114 Controller Driver or UHCI (for Via motherboards) Host Controller
117 You may want to read <file:Documentation/usb/ehci.rst>.
119 To compile this driver as a module, choose M here: the
120 module will be called ehci-hcd.
122 config USB_EHCI_ROOT_HUB_TT
123 bool "Root Hub Transaction Translators"
124 depends on USB_EHCI_HCD
126 Some EHCI chips have vendor-specific extensions to integrate
127 transaction translators, so that no OHCI or UHCI companion
128 controller is needed. It's safe to say "y" even if your
129 controller doesn't support this feature.
131 This supports the EHCI implementation that's originally
132 from ARC, and has since changed hands a few times.
134 config USB_EHCI_TT_NEWSCHED
135 bool "Improved Transaction Translator scheduling"
136 depends on USB_EHCI_HCD
139 This changes the periodic scheduling code to fill more of the low
140 and full speed bandwidth available from the Transaction Translator
141 (TT) in USB 2.0 hubs. Without this, only one transfer will be
142 issued in each microframe, significantly reducing the number of
143 periodic low/fullspeed transfers possible.
145 If you have multiple periodic low/fullspeed devices connected to a
146 highspeed USB hub which is connected to a highspeed USB Host
147 Controller, and some of those devices will not work correctly
148 (possibly due to "ENOSPC" or "-28" errors), say Y. Conversely, if
149 you have only one such device and it doesn't work, you could try

752 Say 'Y' to enable additional software test modes that may be
753 supported by the host controller drivers.
755 One such test mode is the Embedded High-speed Host Electrical Test
756 (EHSET) for EHCI host controller hardware, specifically the "Single
757 Step Set Feature" test. Typically this will be enabled for On-the-Go
758 or embedded hosts that need to undergo USB-IF compliance testing with
759 the aid of special testing hardware. In the future, this may expand
760 to include other tests that require support from a HCD driver.
762 This option is of interest only to developers who need to validate
763 their USB hardware designs. It is not needed for normal use. If
