Ports 53 will connect to EHCI if the device is high speed, otherwise they 54 connect to a companion controller. If you configure EHCI, you should 55 probably configure the OHCI (for NEC and some other vendors) USB Host 56 Controller Driver or UHCI (for Via motherboards) Host Controller 57 Driver too. 58 59 You may want to read <file:Documentation/usb/ehci.txt>. 60 61config USB_EHCI 62 bool 63 default USB_EHCI_HCD 64 ---help--- 65 TODO: rename after most boards switch to Kconfig 66 67if USB_EHCI_HCD 68 69config USB_EHCI_ATMEL 70 bool "Support for Atmel on-chip EHCI USB controller" 71 depends on ARCH_AT91 72 default y 73 ---help--- 74 Enables support for the on-chip EHCI controller on Atmel chips. 75 76config USB_EHCI_MARVELL 77 bool "Support for MVEBU (AXP / A38x) on-chip EHCI USB controller" 78 depends on ARCH_MVEBU 79 default y 80 ---help--- 81 Enables support for the on-chip EHCI controller on MVEBU SoCs. 82 83config USB_EHCI_MX6 84 bool "Support for i.MX6 on-chip EHCI USB controller" 85 depends on ARCH_MX6 86 default y 87 ---help--- 88 Enables support for the on-chip EHCI controller on i.MX6 SoCs. 89 90config USB_EHCI_MX7 91 bool "Support for i.MX7 on-chip EHCI USB controller" 92 depends on ARCH_MX7 93 default y 94 ---help--- 95 Enables support for the on-chip EHCI controller on i.MX7 SoCs. 96 97if USB_EHCI_MX7 98 99config MXC_USB_OTG_HACTIVE 100 bool "USB Power pin high active" 101 ---help--- 102 Set the USB Power pin polarity to be high active (PWR_POL) 103 104endif 105 106config USB_EHCI_MSM 107 bool "Support for Qualcomm on-chip EHCI USB controller" 108 depends on DM_USB 109 select USB_ULPI_VIEWPORT 110 default n 111 ---help--- 112 Enables support for the on-chip EHCI controller on Qualcomm 113 Snapdragon SoCs. 114 This driver supports combination of Chipidea USB controller 115 and Synapsys USB PHY in host mode only. 116 117config USB_EHCI_ZYNQ 118 bool "Support for Xilinx Zynq on-chip EHCI USB controller" 119 depends on ARCH_ZYNQ 120 default y 121 ---help--- 122 Enable support for Zynq on-chip EHCI USB controller 123 124config USB_EHCI_GENERIC 125 bool "Support for generic EHCI USB controller" 126 depends on OF_CONTROL 127 depends on DM_USB 128 default n 129 ---help--- 130 Enables support for generic EHCI controller. 131 132endif # USB_EHCI_HCD 133 134config USB_OHCI_HCD 135 bool "OHCI HCD (USB 1.1) support" 136 ---help--- 137 The Open Host Controller Interface (OHCI) is a standard for accessing 138 USB 1.1 host controller hardware.

On most non-x86 systems, and on x86 hardware that's not using a 141 USB controller from Intel or VIA, this is appropriate. If your host 142 controller doesn't use PCI, this is probably appropriate. For a PCI 143 based system where you're not sure, the "lspci -v" entry will list the 144 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI. 145 146if USB_OHCI_HCD 147 148config USB_OHCI_GENERIC 149 bool "Support for generic OHCI USB controller" 150 depends on OF_CONTROL 151 depends on DM_USB 152 select USB_HOST 153 ---help--- 154 Enables support for generic OHCI controller. 155 156endif # USB_OHCI_HCD 157 158config USB_UHCI_HCD 159 bool "UHCI HCD (most Intel and VIA) support" 160 select USB_HOST 161 ---help--- 162 The Universal Host Controller Interface is a standard by Intel for 163 accessing the USB hardware in the PC (which is also called the USB 164 host controller). If your USB host controller conforms to this 165 standard, you may want to say Y, but see below. All recent boards 166 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, 167 i810, i820) conform to this standard. Also all VIA PCI chipsets 168 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro 169 133) and LEON/GRLIB SoCs with the GRUSBHC controller. 170 If unsure, say Y. 171 172if USB_UHCI_HCD 173 174endif # USB_UHCI_HCD 175
