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_MARVELL 56 bool "Support for MVEBU (AXP / A38x) on-chip EHCI USB controller" 57 depends on ARCH_MVEBU 58 default y 59 ---help--- 60 Enables support for the on-chip EHCI controller on MVEBU SoCs. 61 62config USB_EHCI_MX6 63 bool "Support for i.MX6 on-chip EHCI USB controller" 64 depends on ARCH_MX6 65 default y 66 ---help--- 67 Enables support for the on-chip EHCI controller on i.MX6 SoCs. 68 69config USB_EHCI_MX7 70 bool "Support for i.MX7 on-chip EHCI USB controller" 71 depends on ARCH_MX7 72 default y 73 ---help--- 74 Enables support for the on-chip EHCI controller on i.MX7 SoCs. 75 76if USB_EHCI_MX7 77 78config MXC_USB_OTG_HACTIVE 79 bool "USB Power pin high active" 80 ---help--- 81 Set the USB Power pin polarity to be high active (PWR_POL) 82 83endif 84 85config USB_EHCI_MSM 86 bool "Support for Qualcomm on-chip EHCI USB controller" 87 depends on DM_USB 88 select USB_ULPI_VIEWPORT 89 default n 90 ---help--- 91 Enables support for the on-chip EHCI controller on Qualcomm 92 Snapdragon SoCs. 93 This driver supports combination of Chipidea USB controller 94 and Synapsys USB PHY in host mode only. 95 96config USB_EHCI_ZYNQ 97 bool "Support for Xilinx Zynq on-chip EHCI USB controller" 98 depends on ARCH_ZYNQ 99 default y 100 ---help--- 101 Enable support for Zynq on-chip EHCI USB controller 102 103config USB_EHCI_GENERIC 104 bool "Support for generic EHCI USB controller" 105 depends on OF_CONTROL 106 depends on DM_USB 107 default n 108 ---help--- 109 Enables support for generic EHCI controller. 110 111endif # USB_EHCI_HCD 112 113config USB_OHCI_HCD 114 bool "OHCI HCD (USB 1.1) support" 115 ---help--- 116 The Open Host Controller Interface (OHCI) is a standard for accessing 117 USB 1.1 host controller hardware.
