-* 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";
-};
