+* Texas Instruments OMAP4+ McPDM
+
+Required properties:
+- compatible: "ti,omap4-mcpdm"
+- reg: Register location and size as an array:
+       <MPU access base address, size>,
+       <L3 interconnect address, size>;
+- interrupts: Interrupt number for McPDM
+- ti,hwmods: Name of the hwmod associated to the McPDM
+- clocks:  phandle for the pdmclk provider, likely <&twl6040>
+- clock-names: Must be "pdmclk"
+
+Example:
+
+mcpdm: mcpdm@40132000 {
+	compatible = "ti,omap4-mcpdm";
+	reg = <0x40132000 0x7f>, /* MPU private access */
+	      <0x49032000 0x7f>; /* L3 Interconnect */
+	interrupts = <0 112 0x4>;
+	interrupt-parent = <&gic>;
+	ti,hwmods = "mcpdm";
+};
+
+In board DTS file the pdmclk needs to be added:
+
+&mcpdm {
+	clocks = <&twl6040>;
+	clock-names = "pdmclk";
+	status = "okay";
+};
