* 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>;
