+* 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";
+};
