   2
   3Required properties:
   4
   5- compatible: should be "ti,usbhs-host"
   6- reg: should contain one register range i.e. start and length
   7- ti,hwmods: must contain "usb_host_hs"
   8
   9Optional properties:
  10
  11- num-ports: number of USB ports. Usually this is automatically detected
  12  from the IP's revision register but can be overridden by specifying
  13  this property. A maximum of 3 ports are supported at the moment.
  14
  15- portN-mode: String specifying the port mode for port N, where N can be
  16  from 1 to 3. If the port mode is not specified, that port is treated
  17  as unused. When specified, it must be one of the following.
  18        "ehci-phy",
  19        "ehci-tll",
  20        "ehci-hsic",
  21        "ohci-phy-6pin-datse0",
  22        "ohci-phy-6pin-dpdm",
  23        "ohci-phy-3pin-datse0",
  24        "ohci-phy-4pin-dpdm",
  25        "ohci-tll-6pin-datse0",
  26        "ohci-tll-6pin-dpdm",
  27        "ohci-tll-3pin-datse0",
  28        "ohci-tll-4pin-dpdm",
  29        "ohci-tll-2pin-datse0",
  30        "ohci-tll-2pin-dpdm",
  31
  32- single-ulpi-bypass: Must be present if the controller contains a single
  33  ULPI bypass control bit. e.g. OMAP3 silicon <= ES2.1
  34
  35Required properties if child node exists:
  36
  37- #address-cells: Must be 1
  38- #size-cells: Must be 1
  39- ranges: must be present
  40
  41Properties for children:

  43The OMAP HS USB Host subsystem contains EHCI and OHCI controllers.
