10 bool "xHCI HCD (USB 3.0) support"
13 The eXtensible Host Controller Interface (xHCI) is standard for USB 3.0
14 "SuperSpeed" host controller hardware.
18 config USB_XHCI_UNIPHIER
19 bool "Support for UniPhier on-chip xHCI USB controller"
20 depends on ARCH_UNIPHIER
23 Enables support for the on-chip xHCI controller on UniPhier SoCs.
26 bool "DesignWare USB3 DRD Core Support"
28 Say Y or if your system has a Dual Role SuperSpeed
29 USB controller based on the DesignWare USB3 IP Core.
34 bool "EHCI HCD (USB 2.0) support"
37 The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
38 "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
39 If your USB host controller supports USB 2.0, you will likely want to
40 configure this Host Controller Driver.
42 EHCI controllers are packaged with "companion" host controllers (OHCI
43 or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
44 will connect to EHCI if the device is high speed, otherwise they
45 connect to a companion controller. If you configure EHCI, you should
46 probably configure the OHCI (for NEC and some other vendors) USB Host
47 Controller Driver or UHCI (for Via motherboards) Host Controller
50 You may want to read <file:Documentation/usb/ehci.txt>.
56 TODO: rename after most boards switch to Kconfig
60 config USB_EHCI_MARVELL
61 bool "Support for MVEBU (AXP / A38x) on-chip EHCI USB controller"
65 Enables support for the on-chip EHCI controller on MVEBU SoCs.
68 bool "Support for i.MX6 on-chip EHCI USB controller"
72 Enables support for the on-chip EHCI controller on i.MX6 SoCs.
75 bool "Support for i.MX7 on-chip EHCI USB controller"
79 Enables support for the on-chip EHCI controller on i.MX7 SoCs.
83 config MXC_USB_OTG_HACTIVE
84 bool "USB Power pin high active"
86 Set the USB Power pin polarity to be high active (PWR_POL)
91 bool "Support for Qualcomm on-chip EHCI USB controller"
93 select USB_ULPI_VIEWPORT
96 Enables support for the on-chip EHCI controller on Qualcomm
98 This driver supports combination of Chipidea USB controller
99 and Synapsys USB PHY in host mode only.
102 bool "Support for Xilinx Zynq on-chip EHCI USB controller"
106 Enable support for Zynq on-chip EHCI USB controller
108 config USB_EHCI_GENERIC
109 bool "Support for generic EHCI USB controller"
110 depends on OF_CONTROL
114 Enables support for generic EHCI controller.
119 bool "OHCI HCD (USB 1.1) support"
121 The Open Host Controller Interface (OHCI) is a standard for accessing
122 USB 1.1 host controller hardware. It does more in hardware than Intel's
123 UHCI specification. If your USB host controller follows the OHCI spec,
124 say Y. On most non-x86 systems, and on x86 hardware that's not using a
125 USB controller from Intel or VIA, this is appropriate. If your host
126 controller doesn't use PCI, this is probably appropriate. For a PCI
127 based system where you're not sure, the "lspci -v" entry will list the
128 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
132 config USB_OHCI_GENERIC
133 bool "Support for generic OHCI USB controller"
134 depends on OF_CONTROL
138 Enables support for generic OHCI controller.
143 bool "UHCI HCD (most Intel and VIA) support"
146 The Universal Host Controller Interface is a standard by Intel for
147 accessing the USB hardware in the PC (which is also called the USB
148 host controller). If your USB host controller conforms to this
149 standard, you may want to say Y, but see below. All recent boards
150 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
151 i810, i820) conform to this standard. Also all VIA PCI chipsets
152 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
153 133) and LEON/GRLIB SoCs with the GRUSBHC controller.
