Ports 32 will connect to EHCI if the device is high speed, otherwise they 33 connect to a companion controller. If you configure EHCI, you should 34 probably configure the OHCI (for NEC and some other vendors) USB Host 35 Controller Driver or UHCI (for Via motherboards) Host Controller 36 Driver too. 37 38 You may want to read <file:Documentation/usb/ehci.txt>. 39 40config USB_EHCI 41 bool 42 default USB_EHCI_HCD 43 ---help--- 44 TODO: rename after most boards switch to Kconfig 45 46if USB_EHCI_HCD 47 48config USB_EHCI_UNIPHIER 49 bool "Support for Panasonic UniPhier on-chip EHCI USB controller" 50 depends on ARCH_UNIPHIER 51 default y 52 ---help--- 53 Enables support for the on-chip EHCI controller on Panasonic 54 UniPhier SoCs. 55 56endif 57
