Ports 60 will connect to EHCI if the device is high speed, otherwise they 61 connect to a companion controller. If you configure EHCI, you should 62 probably configure the OHCI (for NEC and some other vendors) USB Host 63 Controller Driver or UHCI (for Via motherboards) Host Controller 64 Driver too. 65 66 You may want to read <file:Documentation/usb/ehci.txt>. 67 68config USB_EHCI 69 bool 70 default USB_EHCI_HCD 71 ---help--- 72 TODO: rename after most boards switch to Kconfig 73 74if USB_EHCI_HCD 75 76config USB_EHCI_ATMEL 77 bool "Support for Atmel on-chip EHCI USB controller" 78 depends on ARCH_AT91 79 default y 80 ---help--- 81 Enables support for the on-chip EHCI controller on Atmel chips. 82 83config USB_EHCI_MARVELL 84 bool "Support for MVEBU (AXP / A38x) on-chip EHCI USB controller" 85 depends on ARCH_MVEBU 86 default y 87 ---help--- 88 Enables support for the on-chip EHCI controller on MVEBU SoCs. 89 90config USB_EHCI_MX6 91 bool "Support for i.MX6 on-chip EHCI USB controller" 92 depends on ARCH_MX6 93 default y 94 ---help--- 95 Enables support for the on-chip EHCI controller on i.MX6 SoCs. 96 97config USB_EHCI_MX7 98 bool "Support for i.MX7 on-chip EHCI USB controller" 99 depends on ARCH_MX7 100 default y 101 ---help--- 102 Enables support for the on-chip EHCI controller on i.MX7 SoCs. 103 104if USB_EHCI_MX7 105 106config MXC_USB_OTG_HACTIVE 107 bool "USB Power pin high active" 108 ---help--- 109 Set the USB Power pin polarity to be high active (PWR_POL) 110 111endif 112 113config USB_EHCI_MSM 114 bool "Support for Qualcomm on-chip EHCI USB controller" 115 depends on DM_USB 116 select USB_ULPI_VIEWPORT 117 default n 118 ---help--- 119 Enables support for the on-chip EHCI controller on Qualcomm 120 Snapdragon SoCs. 121 This driver supports combination of Chipidea USB controller 122 and Synapsys USB PHY in host mode only. 123 124config USB_EHCI_ZYNQ 125 bool "Support for Xilinx Zynq on-chip EHCI USB controller" 126 depends on ARCH_ZYNQ 127 default y 128 ---help--- 129 Enable support for Zynq on-chip EHCI USB controller 130 131config USB_EHCI_GENERIC 132 bool "Support for generic EHCI USB controller" 133 depends on OF_CONTROL 134 depends on DM_USB 135 default n 136 ---help--- 137 Enables support for generic EHCI controller. 138 139endif # USB_EHCI_HCD 140 141config USB_OHCI_HCD 142 bool "OHCI HCD (USB 1.1) support" 143 ---help--- 144 The Open Host Controller Interface (OHCI) is a standard for accessing 145 USB 1.1 host controller hardware.

On most non-x86 systems, and on x86 hardware that's not using a 148 USB controller from Intel or VIA, this is appropriate. If your host 149 controller doesn't use PCI, this is probably appropriate. For a PCI 150 based system where you're not sure, the "lspci -v" entry will list the 151 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI. 152 153if USB_OHCI_HCD 154 155config USB_OHCI_GENERIC 156 bool "Support for generic OHCI USB controller" 157 depends on OF_CONTROL 158 depends on DM_USB 159 select USB_HOST 160 ---help--- 161 Enables support for generic OHCI controller. 162 163endif # USB_OHCI_HCD 164 165config USB_UHCI_HCD 166 bool "UHCI HCD (most Intel and VIA) support" 167 select USB_HOST 168 ---help--- 169 The Universal Host Controller Interface is a standard by Intel for 170 accessing the USB hardware in the PC (which is also called the USB 171 host controller).

All recent boards 173 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, 174 i810, i820) conform to this standard. Also all VIA PCI chipsets 175 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro 176 133) and LEON/GRLIB SoCs with the GRUSBHC controller. 177 If unsure, say Y. 178 179if USB_UHCI_HCD 180 181endif # USB_UHCI_HCD 182
