This device is usually the child of the omap-usb-host
Documentation/devicetree/bindings/mfd/omap-usb-host.txt

Required properties:

- compatible: should be "ti,ehci-omap"
- reg: should contain one register range i.e. start and length
- interrupts: description of the interrupt line

Optional properties:

- phys: list of phandles to PHY nodes.
  This property is required if at least one of the ports are in
  PHY mode i.e. OMAP_EHCI_PORT_MODE_PHY

To specify the port mode, see
Documentation/devicetree/bindings/mfd/omap-usb-host.txt

Example for OMAP4:

usbhsehci: ehci@4a064c00 {
	compatible = "ti,ehci-omap";
	reg = <0x4a064c00 0x400>;
	interrupts = <0 77 0x4>;
};

&usbhsehci {
	phys = <&hsusb1_phy 0 &hsusb3_phy>;
};
