* 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

- interrupt-parent: The parent interrupt controller

- ti,hwmods: Name of the hwmod associated to the McPDM



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";

};
