+* Texas Instruments OMAP4+ Digital Microphone Module
+
+Required properties:
+- compatible: "ti,omap4-dmic"
+- reg: Register location and size as an array:
+ <MPU access base address, size>,
+ <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";
+};
