+* 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 at 31020000 {
+ compatible = "nxp,ohci-nxp";
+ reg = <0x31020000 0x300>;
+ interrupt-parent = <&mic>;
