* 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";
};
