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"
29 Choose this option to add support for USB 3.0 driver on mvebu
30 SoCs, which includes Armada8K, Armada3700 and other Armada
33 config USB_XHCI_ROCKCHIP
34 bool "Support for Rockchip on-chip xHCI USB controller"
35 depends on ARCH_ROCKCHIP
38 Enables support for the on-chip xHCI controller on Rockchip SoCs.
43 bool "EHCI HCD (USB 2.0) support"
46 The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
47 "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
48 If your USB host controller supports USB 2.0, you will likely want to
49 configure this Host Controller Driver.
51 EHCI controllers are packaged with "companion" host controllers (OHCI
52 or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
53 will connect to EHCI if the device is high speed, otherwise they
54 connect to a companion controller. If you configure EHCI, you should
55 probably configure the OHCI (for NEC and some other vendors) USB Host
56 Controller Driver or UHCI (for Via motherboards) Host Controller
59 You may want to read <file:Documentation/usb/ehci.txt>.
65 TODO: rename after most boards switch to Kconfig
70 bool "Support for Atmel on-chip EHCI USB controller"
74 Enables support for the on-chip EHCI controller on Atmel chips.
76 config USB_EHCI_MARVELL
77 bool "Support for MVEBU (AXP / A38x) on-chip EHCI USB controller"
81 Enables support for the on-chip EHCI controller on MVEBU SoCs.
84 bool "Support for i.MX6 on-chip EHCI USB controller"
88 Enables support for the on-chip EHCI controller on i.MX6 SoCs.
91 bool "Support for i.MX7 on-chip EHCI USB controller"
95 Enables support for the on-chip EHCI controller on i.MX7 SoCs.
99 config MXC_USB_OTG_HACTIVE
100 bool "USB Power pin high active"
102 Set the USB Power pin polarity to be high active (PWR_POL)
107 bool "Support for Qualcomm on-chip EHCI USB controller"
109 select USB_ULPI_VIEWPORT
112 Enables support for the on-chip EHCI controller on Qualcomm
114 This driver supports combination of Chipidea USB controller
115 and Synapsys USB PHY in host mode only.
118 bool "Support for Xilinx Zynq on-chip EHCI USB controller"
122 Enable support for Zynq on-chip EHCI USB controller
124 config USB_EHCI_GENERIC
125 bool "Support for generic EHCI USB controller"
126 depends on OF_CONTROL
130 Enables support for generic EHCI controller.
135 bool "OHCI HCD (USB 1.1) support"
137 The Open Host Controller Interface (OHCI) is a standard for accessing
138 USB 1.1 host controller hardware. It does more in hardware than Intel's
139 UHCI specification. If your USB host controller follows the OHCI spec,
140 say Y. On most non-x86 systems, and on x86 hardware that's not using a
141 USB controller from Intel or VIA, this is appropriate. If your host
142 controller doesn't use PCI, this is probably appropriate. For a PCI
143 based system where you're not sure, the "lspci -v" entry will list the
144 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
148 config USB_OHCI_GENERIC
149 bool "Support for generic OHCI USB controller"
150 depends on OF_CONTROL
154 Enables support for generic OHCI controller.
159 bool "UHCI HCD (most Intel and VIA) support"
162 The Universal Host Controller Interface is a standard by Intel for
163 accessing the USB hardware in the PC (which is also called the USB
164 host controller). If your USB host controller conforms to this
165 standard, you may want to say Y, but see below. All recent boards
166 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
167 i810, i820) conform to this standard. Also all VIA PCI chipsets
168 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
169 133) and LEON/GRLIB SoCs with the GRUSBHC controller.
