Ports 69 will connect to EHCI if the device is high speed, otherwise they 70 connect to a companion controller. If you configure EHCI, you should 71 probably configure the OHCI (for NEC and some other vendors) USB Host 72 Controller Driver or UHCI (for Via motherboards) Host Controller 73 Driver too. 74 75 You may want to read <file:Documentation/usb/ehci.txt>. 76 77if USB_EHCI_HCD 78 79config USB_EHCI_ATMEL 80 bool "Support for Atmel on-chip EHCI USB controller" 81 depends on ARCH_AT91 82 default y 83 ---help--- 84 Enables support for the on-chip EHCI controller on Atmel chips. 85 86config USB_EHCI_MARVELL 87 bool "Support for MVEBU (AXP / A38x) on-chip EHCI USB controller" 88 depends on ARCH_MVEBU 89 default y 90 ---help--- 91 Enables support for the on-chip EHCI controller on MVEBU SoCs. 92 93config USB_EHCI_MX6 94 bool "Support for i.MX6 on-chip EHCI USB controller" 95 depends on ARCH_MX6 96 default y 97 ---help--- 98 Enables support for the on-chip EHCI controller on i.MX6 SoCs. 99 100config USB_EHCI_MX7 101 bool "Support for i.MX7 on-chip EHCI USB controller" 102 depends on ARCH_MX7 103 default y 104 ---help--- 105 Enables support for the on-chip EHCI controller on i.MX7 SoCs. 106 107if USB_EHCI_MX7 108 109config MXC_USB_OTG_HACTIVE 110 bool "USB Power pin high active" 111 ---help--- 112 Set the USB Power pin polarity to be high active (PWR_POL) 113 114endif 115 116config USB_EHCI_MSM 117 bool "Support for Qualcomm on-chip EHCI USB controller" 118 depends on DM_USB 119 select USB_ULPI_VIEWPORT 120 default n 121 ---help--- 122 Enables support for the on-chip EHCI controller on Qualcomm 123 Snapdragon SoCs. 124 This driver supports combination of Chipidea USB controller 125 and Synapsys USB PHY in host mode only. 126 127config USB_EHCI_ZYNQ 128 bool "Support for Xilinx Zynq on-chip EHCI USB controller" 129 depends on ARCH_ZYNQ 130 default y 131 ---help--- 132 Enable support for Zynq on-chip EHCI USB controller 133 134config USB_EHCI_GENERIC 135 bool "Support for generic EHCI USB controller" 136 depends on OF_CONTROL 137 depends on DM_USB 138 default n 139 ---help--- 140 Enables support for generic EHCI controller. 141 142endif # USB_EHCI_HCD 143 144config USB_OHCI_HCD 145 bool "OHCI HCD (USB 1.1) support" 146 ---help--- 147 The Open Host Controller Interface (OHCI) is a standard for accessing 148 USB 1.1 host controller hardware.

All recent boards 176 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, 177 i810, i820) conform to this standard. Also all VIA PCI chipsets 178 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro 179 133) and LEON/GRLIB SoCs with the GRUSBHC controller. 180 If unsure, say Y. 181 182if USB_UHCI_HCD 183 184endif # USB_UHCI_HCD 185
