* Texas Instruments OMAP4+ McPDM Required properties: - compatible: "ti,omap4-mcpdm" - reg: Register location and size as an array: , ; - 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"; };
