   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 - interrupt-parent: The parent interrupt controller
  10 - ti,hwmods: Name of the hwmod associated to the McPDM
  11 - clocks:  phandle for the pdmclk provider, likely <&twl6040>
  12 - clock-names: Must be "pdmclk"
  13
  14 Example:
  15
  16 mcpdm: mcpdm@40132000 {
  17         compatible = "ti,omap4-mcpdm";
  18         reg = <0x40132000 0x7f>, /* MPU private access */
  19               <0x49032000 0x7f>; /* L3 Interconnect */
  20         interrupts = <0 112 0x4>;
  21         interrupt-parent = <&gic>;
  22         ti,hwmods = "mcpdm";
  23 };
  24
  25 In board DTS file the pdmclk needs to be added:
  26
  27 &mcpdm {
  28         clocks = <&twl6040>;
  29         clock-names = "pdmclk";
  30         status = "okay";
  31 };
