* OHCI controller, NXP ohci-nxp variant



Required properties:

- compatible: must be "nxp,ohci-nxp"

- reg: physical base address of the controller and length of memory mapped

  region.

- interrupts: The OHCI interrupt



Example (LPC32xx):



	ohci@31020000 {

		compatible = "nxp,ohci-nxp";

		reg = <0x31020000 0x300>;

		interrupt-parent = <&mic>;

		interrupts = <0x3b 0>;

	};
