Required properties:
- compatible: "ti,omap4-dmic"
- reg: Register location and size as an array:

       <L3 interconnect address, size>;
- interrupts: Interrupt number for DMIC
- interrupt-parent: The parent interrupt controller
- ti,hwmods: Name of the hwmod associated with OMAP dmic IP

Example:

dmic: dmic@4012e000 {
	compatible = "ti,omap4-dmic";
	reg = <0x4012e000 0x7f>, /* MPU private access */
	      <0x4902e000 0x7f>; /* L3 Interconnect */
	interrupts = <0 114 0x4>;
	interrupt-parent = <&gic>;
	ti,hwmods = "dmic";
};
