+* 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
+- transceiver: phandle of the associated ISP1301 device - this is necessary for
+               the UDC controller for connecting to the USB physical layer
+
+Example (LPC32xx):
+
+	isp1301: usb-transceiver@2c {
+		compatible = "nxp,isp1301";
+		reg = <0x2c>;
+	};
+
+	ohci@31020000 {
+		compatible = "nxp,ohci-nxp";
+		reg = <0x31020000 0x300>;
+		interrupt-parent = <&mic>;
+		interrupts = <0x3b 0>;
+		transceiver = <&isp1301>;
+	};
