Ports 59 will connect to EHCI if the device is high speed, otherwise they 60 connect to a companion controller. If you configure EHCI, you should 61 probably configure the OHCI (for NEC and some other vendors) USB Host 62 Controller Driver or UHCI (for Via motherboards) Host Controller 63 Driver too. 64 65 You may want to read <file:Documentation/usb/ehci.txt>. 66 67config USB_EHCI 68 bool 69 default USB_EHCI_HCD 70 ---help--- 71 TODO: rename after most boards switch to Kconfig 72 73if USB_EHCI_HCD 74 75config USB_EHCI_ATMEL 76 bool "Support for Atmel on-chip EHCI USB controller" 77 depends on ARCH_AT91 78 default y 79 ---help--- 80 Enables support for the on-chip EHCI controller on Atmel chips. 81 82config USB_EHCI_MARVELL 83 bool "Support for MVEBU (AXP / A38x) on-chip EHCI USB controller" 84 depends on ARCH_MVEBU 85 default y 86 ---help--- 87 Enables support for the on-chip EHCI controller on MVEBU SoCs. 88 89config USB_EHCI_MX6 90 bool "Support for i.MX6 on-chip EHCI USB controller" 91 depends on ARCH_MX6 92 default y 93 ---help--- 94 Enables support for the on-chip EHCI controller on i.MX6 SoCs. 95 96config USB_EHCI_MX7 97 bool "Support for i.MX7 on-chip EHCI USB controller" 98 depends on ARCH_MX7 99 default y 100 ---help--- 101 Enables support for the on-chip EHCI controller on i.MX7 SoCs. 102 103if USB_EHCI_MX7 104 105config MXC_USB_OTG_HACTIVE 106 bool "USB Power pin high active" 107 ---help--- 108 Set the USB Power pin polarity to be high active (PWR_POL) 109 110endif 111 112config USB_EHCI_MSM 113 bool "Support for Qualcomm on-chip EHCI USB controller" 114 depends on DM_USB 115 select USB_ULPI_VIEWPORT 116 default n 117 ---help--- 118 Enables support for the on-chip EHCI controller on Qualcomm 119 Snapdragon SoCs. 120 This driver supports combination of Chipidea USB controller 121 and Synapsys USB PHY in host mode only. 122 123config USB_EHCI_ZYNQ 124 bool "Support for Xilinx Zynq on-chip EHCI USB controller" 125 depends on ARCH_ZYNQ 126 default y 127 ---help--- 128 Enable support for Zynq on-chip EHCI USB controller 129 130config USB_EHCI_GENERIC 131 bool "Support for generic EHCI USB controller" 132 depends on OF_CONTROL 133 depends on DM_USB 134 default n 135 ---help--- 136 Enables support for generic EHCI controller. 137 138endif # USB_EHCI_HCD 139 140config USB_OHCI_HCD 141 bool "OHCI HCD (USB 1.1) support" 142 ---help--- 143 The Open Host Controller Interface (OHCI) is a standard for accessing 144 USB 1.1 host controller hardware.

All recent boards 172 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, 173 i810, i820) conform to this standard. Also all VIA PCI chipsets 174 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro 175 133) and LEON/GRLIB SoCs with the GRUSBHC controller. 176 If unsure, say Y. 177 178if USB_UHCI_HCD 179 180endif # USB_UHCI_HCD 181
