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_MX7 78 bool "Support for i.MX7 on-chip EHCI USB controller" 79 depends on ARCH_MX7 80 default y 81 ---help--- 82 Enables support for the on-chip EHCI controller on i.MX7 SoCs. 83 84if USB_EHCI_MX7 85 86config MXC_USB_OTG_HACTIVE 87 bool "USB Power pin high active" 88 ---help--- 89 Set the USB Power pin polarity to be high active (PWR_POL) 90 91endif 92 93config USB_EHCI_MSM 94 bool "Support for Qualcomm on-chip EHCI USB controller" 95 depends on DM_USB 96 select USB_ULPI_VIEWPORT 97 default n 98 ---help--- 99 Enables support for the on-chip EHCI controller on Qualcomm 100 Snapdragon SoCs. 101 This driver supports combination of Chipidea USB controller 102 and Synapsys USB PHY in host mode only. 103 104config USB_EHCI_ZYNQ 105 bool "Support for Xilinx Zynq on-chip EHCI USB controller" 106 depends on ARCH_ZYNQ 107 default y 108 ---help--- 109 Enable support for Zynq on-chip EHCI USB controller 110 111config USB_EHCI_GENERIC 112 bool "Support for generic EHCI USB controller" 113 depends on OF_CONTROL 114 depends on DM_USB 115 default n 116 ---help--- 117 Enables support for generic EHCI controller. 118 119endif 120
