Changelog v6:
- Add dma property
- Add dma-names property
- Add reg-names property
- Remove ti,hwmods completely (no longer needed since the sysc
conversion)
- Update example to match one in DTS

Changelog v5:
- Add imports for constants
- Add desc to ti,hwmods

Changelog v4:
- Changed maintainer name
- Use $ref and enum in ti-hwmods property
- Make clocks property only have maxItems, no description
- Add items to clock-names
- Fix address of node in example
- Remove extra line

-* 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";
-};
