    1 * Texas Instruments OMAP4+ McPDM
    2 
    3 Required properties:
    4 - compatible: "ti,omap4-mcpdm"
    5 - reg: Register location and size as an array:
    6        <MPU access base address, size>,
    7        <L3 interconnect address, size>;
    8 - interrupts: Interrupt number for McPDM
    9 - ti,hwmods: Name of the hwmod associated to the McPDM
   10 - clocks:  phandle for the pdmclk provider, likely <&twl6040>
   11 - clock-names: Must be "pdmclk"
   12 
   13 Example:
   14 
   15 mcpdm: mcpdm@40132000 {
   16         compatible = "ti,omap4-mcpdm";
   17         reg = <0x40132000 0x7f>, /* MPU private access */
   18               <0x49032000 0x7f>; /* L3 Interconnect */
   19         interrupts = <0 112 0x4>;
   20         interrupt-parent = <&gic>;
   21         ti,hwmods = "mcpdm";
   22 };
   23 
   24 In board DTS file the pdmclk needs to be added:
   25 
   26 &mcpdm {
   27         clocks = <&twl6040>;
   28         clock-names = "pdmclk";
   29         status = "okay";
   30 };
