USB xHCI controllers



Required properties:

  - compatible: should be "xhci-platform".

  - reg: should contain address and length of the standard XHCI

    register set for the device.

  - interrupts: one XHCI interrupt should be described here.



Example:

	usb@f0931000 {

		compatible = "xhci-platform";

		reg = <0xf0931000 0x8c8>;

		interrupts = <0x0 0x4e 0x0>;

	};
