- interrupts: Interrupt number for McPDM
- interrupt-parent: The parent interrupt controller
- ti,hwmods: Name of the hwmod associated to the McPDM
-- clocks: phandle for the pdmclk provider, likely <&twl6040>
-- clock-names: Must be "pdmclk"
Example:
interrupt-parent = <&gic>;
ti,hwmods = "mcpdm";
};

-In board DTS file the pdmclk needs to be added:
-
-&mcpdm {
- clocks = <&twl6040>;
- clock-names = "pdmclk";
- status = "okay";
-};
