Ports 47 will connect to EHCI if the device is high speed, otherwise they 48 connect to a companion controller. If you configure EHCI, you should 49 probably configure the OHCI (for NEC and some other vendors) USB Host 50 Controller Driver or UHCI (for Via motherboards) Host Controller 51 Driver too. 52 53 You may want to read <file:Documentation/usb/ehci.txt>. 54 55config USB_EHCI 56 bool 57 default USB_EHCI_HCD 58 ---help--- 59 TODO: rename after most boards switch to Kconfig 60 61if USB_EHCI_HCD 62 63config USB_EHCI_MARVELL 64 bool "Support for MVEBU (AXP / A38x) on-chip EHCI USB controller" 65 depends on ARCH_MVEBU 66 default y 67 ---help--- 68 Enables support for the on-chip EHCI controller on MVEBU SoCs. 69 70config USB_EHCI_MX6 71 bool "Support for i.MX6 on-chip EHCI USB controller" 72 depends on ARCH_MX6 73 default y 74 ---help--- 75 Enables support for the on-chip EHCI controller on i.MX6 SoCs. 76 77config USB_EHCI_UNIPHIER 78 bool "Support for UniPhier on-chip EHCI USB controller" 79 depends on ARCH_UNIPHIER && OF_CONTROL 80 default y 81 ---help--- 82 Enables support for the on-chip EHCI controller on UniPhier SoCs. 83 84config USB_EHCI_GENERIC 85 bool "Support for generic EHCI USB controller" 86 depends on OF_CONTROL 87 depends on DM_USB 88 default n 89 ---help--- 90 Enables support for generic EHCI controller. 91 92endif 93
