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