Most Renesas ARM SoCs have a Product Register that allows to retrieve SoC

product and revision information.  If present, a device node for this register

should be added.



Required properties:

  - compatible: Must be "renesas,prr".

  - reg: Base address and length of the register block.





Examples

--------



	prr: chipid@ff000044 {

		compatible = "renesas,prr";

		reg = <0 0xff000044 0 4>;

	};
