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.
19 bool "DesignWare USB3 DRD Core Support"
21 Say Y or if your system has a Dual Role SuperSpeed
22 USB controller based on the DesignWare USB3 IP Core.
25 bool "MVEBU USB 3.0 support"
30 Choose this option to add support for USB 3.0 driver on mvebu
31 SoCs, which includes Armada8K, Armada3700 and other Armada
34 config USB_XHCI_ROCKCHIP
35 bool "Support for Rockchip on-chip xHCI USB controller"
36 depends on ARCH_ROCKCHIP
39 Enables support for the on-chip xHCI controller on Rockchip SoCs.
41 config USB_XHCI_ZYNQMP
42 bool "Support for Xilinx ZynqMP on-chip xHCI USB controller"
43 depends on ARCH_ZYNQMP
45 Enables support for the on-chip xHCI controller on Xilinx ZynqMP SoCs.
50 bool "EHCI HCD (USB 2.0) support"
53 The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
54 "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
55 If your USB host controller supports USB 2.0, you will likely want to
56 configure this Host Controller Driver.
58 EHCI controllers are packaged with "companion" host controllers (OHCI
59 or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
60 will connect to EHCI if the device is high speed, otherwise they
61 connect to a companion controller. If you configure EHCI, you should
62 probably configure the OHCI (for NEC and some other vendors) USB Host
63 Controller Driver or UHCI (for Via motherboards) Host Controller
66 You may want to read <file:Documentation/usb/ehci.txt>.
72 TODO: rename after most boards switch to Kconfig
77 bool "Support for Atmel on-chip EHCI USB controller"
81 Enables support for the on-chip EHCI controller on Atmel chips.
83 config USB_EHCI_MARVELL
84 bool "Support for MVEBU (AXP / A38x) on-chip EHCI USB controller"
88 Enables support for the on-chip EHCI controller on MVEBU SoCs.
91 bool "Support for i.MX6 on-chip EHCI USB controller"
95 Enables support for the on-chip EHCI controller on i.MX6 SoCs.
98 bool "Support for i.MX7 on-chip EHCI USB controller"
102 Enables support for the on-chip EHCI controller on i.MX7 SoCs.
106 config MXC_USB_OTG_HACTIVE
107 bool "USB Power pin high active"
109 Set the USB Power pin polarity to be high active (PWR_POL)
114 bool "Support for Qualcomm on-chip EHCI USB controller"
116 select USB_ULPI_VIEWPORT
119 Enables support for the on-chip EHCI controller on Qualcomm
121 This driver supports combination of Chipidea USB controller
122 and Synapsys USB PHY in host mode only.
125 bool "Support for Xilinx Zynq on-chip EHCI USB controller"
129 Enable support for Zynq on-chip EHCI USB controller
131 config USB_EHCI_GENERIC
132 bool "Support for generic EHCI USB controller"
133 depends on OF_CONTROL
137 Enables support for generic EHCI controller.
142 bool "OHCI HCD (USB 1.1) support"
144 The Open Host Controller Interface (OHCI) is a standard for accessing
145 USB 1.1 host controller hardware. It does more in hardware than Intel's
146 UHCI specification. If your USB host controller follows the OHCI spec,
147 say Y. On most non-x86 systems, and on x86 hardware that's not using a
148 USB controller from Intel or VIA, this is appropriate. If your host
149 controller doesn't use PCI, this is probably appropriate. For a PCI
150 based system where you're not sure, the "lspci -v" entry will list the
151 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
155 config USB_OHCI_GENERIC
156 bool "Support for generic OHCI USB controller"
157 depends on OF_CONTROL
161 Enables support for generic OHCI controller.
166 bool "UHCI HCD (most Intel and VIA) support"
169 The Universal Host Controller Interface is a standard by Intel for
170 accessing the USB hardware in the PC (which is also called the USB
171 host controller). If your USB host controller conforms to this
172 standard, you may want to say Y, but see below. All recent boards
173 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
174 i810, i820) conform to this standard. Also all VIA PCI chipsets
175 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
176 133) and LEON/GRLIB SoCs with the GRUSBHC controller.
