   1 OMAP HS USB Host
   2
   3 Required 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
   9 Optional 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
  35 Required properties if child node exists:
  36
  37 - #address-cells: Must be 1
  38 - #size-cells: Must be 1
  39 - ranges: must be present
  40
  41 Properties for children:
  42
  43 The OMAP HS USB Host subsystem contains EHCI and OHCI controllers.
