Ports 37 will connect to EHCI if the device is high speed, otherwise they 38 connect to a companion controller. If you configure EHCI, you should 39 probably configure the OHCI (for NEC and some other vendors) USB Host 40 Controller Driver or UHCI (for Via motherboards) Host Controller 41 Driver too. 42 43 You may want to read <file:Documentation/usb/ehci.txt>. 44 45config USB_EHCI 46 bool 47 default USB_EHCI_HCD 48 ---help--- 49 TODO: rename after most boards switch to Kconfig 50 51if USB_EHCI_HCD 52 53config USB_EHCI_ATMEL 54 bool "Support for Atmel on-chip EHCI USB controller" 55 depends on ARCH_AT91 56 default y 57 ---help--- 58 Enables support for the on-chip EHCI controller on Atmel chips. 59 60config USB_EHCI_MARVELL 61 bool "Support for MVEBU (AXP / A38x) on-chip EHCI USB controller" 62 depends on ARCH_MVEBU 63 default y 64 ---help--- 65 Enables support for the on-chip EHCI controller on MVEBU SoCs. 66 67config USB_EHCI_MX6 68 bool "Support for i.MX6 on-chip EHCI USB controller" 69 depends on ARCH_MX6 70 default y 71 ---help--- 72 Enables support for the on-chip EHCI controller on i.MX6 SoCs. 73 74config USB_EHCI_MX7 75 bool "Support for i.MX7 on-chip EHCI USB controller" 76 depends on ARCH_MX7 77 default y 78 ---help--- 79 Enables support for the on-chip EHCI controller on i.MX7 SoCs. 80 81if USB_EHCI_MX7 82 83config MXC_USB_OTG_HACTIVE 84 bool "USB Power pin high active" 85 ---help--- 86 Set the USB Power pin polarity to be high active (PWR_POL) 87 88endif 89 90config USB_EHCI_MSM 91 bool "Support for Qualcomm on-chip EHCI USB controller" 92 depends on DM_USB 93 select USB_ULPI_VIEWPORT 94 default n 95 ---help--- 96 Enables support for the on-chip EHCI controller on Qualcomm 97 Snapdragon SoCs. 98 This driver supports combination of Chipidea USB controller 99 and Synapsys USB PHY in host mode only. 100 101config USB_EHCI_ZYNQ 102 bool "Support for Xilinx Zynq on-chip EHCI USB controller" 103 depends on ARCH_ZYNQ 104 default y 105 ---help--- 106 Enable support for Zynq on-chip EHCI USB controller 107 108config USB_EHCI_GENERIC 109 bool "Support for generic EHCI USB controller" 110 depends on OF_CONTROL 111 depends on DM_USB 112 default n 113 ---help--- 114 Enables support for generic EHCI controller. 115 116endif # USB_EHCI_HCD 117 118config USB_OHCI_HCD 119 bool "OHCI HCD (USB 1.1) support" 120 ---help--- 121 The Open Host Controller Interface (OHCI) is a standard for accessing 122 USB 1.1 host controller hardware.

On most non-x86 systems, and on x86 hardware that's not using a 125 USB controller from Intel or VIA, this is appropriate. If your host 126 controller doesn't use PCI, this is probably appropriate. For a PCI 127 based system where you're not sure, the "lspci -v" entry will list the 128 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI. 129 130if USB_OHCI_HCD 131 132config USB_OHCI_GENERIC 133 bool "Support for generic OHCI USB controller" 134 depends on OF_CONTROL 135 depends on DM_USB 136 select USB_HOST 137 ---help--- 138 Enables support for generic OHCI controller. 139 140endif # USB_OHCI_HCD 141 142config USB_UHCI_HCD 143 bool "UHCI HCD (most Intel and VIA) support" 144 select USB_HOST 145 ---help--- 146 The Universal Host Controller Interface is a standard by Intel for 147 accessing the USB hardware in the PC (which is also called the USB 148 host controller). If your USB host controller conforms to this 149 standard, you may want to say Y, but see below. All recent boards 150 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, 151 i810, i820) conform to this standard. Also all VIA PCI chipsets 152 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro 153 133) and LEON/GRLIB SoCs with the GRUSBHC controller. 154 If unsure, say Y. 155 156if USB_UHCI_HCD 157 158endif # USB_UHCI_HCD 159
