Ports 44 will connect to EHCI if the device is high speed, otherwise they 45 connect to a companion controller. If you configure EHCI, you should 46 probably configure the OHCI (for NEC and some other vendors) USB Host 47 Controller Driver or UHCI (for Via motherboards) Host Controller 48 Driver too. 49 50 You may want to read <file:Documentation/usb/ehci.txt>. 51 52config USB_EHCI 53 bool 54 default USB_EHCI_HCD 55 ---help--- 56 TODO: rename after most boards switch to Kconfig 57 58if USB_EHCI_HCD 59 60config USB_EHCI_ATMEL 61 bool "Support for Atmel on-chip EHCI USB controller" 62 depends on ARCH_AT91 63 default y 64 ---help--- 65 Enables support for the on-chip EHCI controller on Atmel chips. 66 67config USB_EHCI_MARVELL 68 bool "Support for MVEBU (AXP / A38x) on-chip EHCI USB controller" 69 depends on ARCH_MVEBU 70 default y 71 ---help--- 72 Enables support for the on-chip EHCI controller on MVEBU SoCs. 73 74config USB_EHCI_MX6 75 bool "Support for i.MX6 on-chip EHCI USB controller" 76 depends on ARCH_MX6 77 default y 78 ---help--- 79 Enables support for the on-chip EHCI controller on i.MX6 SoCs. 80 81config USB_EHCI_MX7 82 bool "Support for i.MX7 on-chip EHCI USB controller" 83 depends on ARCH_MX7 84 default y 85 ---help--- 86 Enables support for the on-chip EHCI controller on i.MX7 SoCs. 87 88if USB_EHCI_MX7 89 90config MXC_USB_OTG_HACTIVE 91 bool "USB Power pin high active" 92 ---help--- 93 Set the USB Power pin polarity to be high active (PWR_POL) 94 95endif 96 97config USB_EHCI_MSM 98 bool "Support for Qualcomm on-chip EHCI USB controller" 99 depends on DM_USB 100 select USB_ULPI_VIEWPORT 101 default n 102 ---help--- 103 Enables support for the on-chip EHCI controller on Qualcomm 104 Snapdragon SoCs. 105 This driver supports combination of Chipidea USB controller 106 and Synapsys USB PHY in host mode only. 107 108config USB_EHCI_ZYNQ 109 bool "Support for Xilinx Zynq on-chip EHCI USB controller" 110 depends on ARCH_ZYNQ 111 default y 112 ---help--- 113 Enable support for Zynq on-chip EHCI USB controller 114 115config USB_EHCI_GENERIC 116 bool "Support for generic EHCI USB controller" 117 depends on OF_CONTROL 118 depends on DM_USB 119 default n 120 ---help--- 121 Enables support for generic EHCI controller. 122 123endif # USB_EHCI_HCD 124 125config USB_OHCI_HCD 126 bool "OHCI HCD (USB 1.1) support" 127 ---help--- 128 The Open Host Controller Interface (OHCI) is a standard for accessing 129 USB 1.1 host controller hardware.

All recent boards 157 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, 158 i810, i820) conform to this standard. Also all VIA PCI chipsets 159 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro 160 133) and LEON/GRLIB SoCs with the GRUSBHC controller. 161 If unsure, say Y. 162 163if USB_UHCI_HCD 164 165endif # USB_UHCI_HCD 166
