Ports 39 will connect to EHCI if the device is high speed, otherwise they 40 connect to a companion controller. If you configure EHCI, you should 41 probably configure the OHCI (for NEC and some other vendors) USB Host 42 Controller Driver or UHCI (for Via motherboards) Host Controller 43 Driver too. 44 45 You may want to read <file:Documentation/usb/ehci.txt>. 46 47config USB_EHCI 48 bool 49 default USB_EHCI_HCD 50 ---help--- 51 TODO: rename after most boards switch to Kconfig 52 53if USB_EHCI_HCD 54 55config USB_EHCI_MX6 56 bool "Support for i.MX6 on-chip EHCI USB controller" 57 depends on ARCH_MX6 58 default y 59 ---help--- 60 Enables support for the on-chip EHCI controller on i.MX6 SoCs. 61 62config USB_EHCI_UNIPHIER 63 bool "Support for UniPhier on-chip EHCI USB controller" 64 depends on ARCH_UNIPHIER && OF_CONTROL 65 default y 66 ---help--- 67 Enables support for the on-chip EHCI controller on UniPhier SoCs. 68 69endif 70
