+Most Renesas ARM SoCs have one or two registers (Common Chip Code
+Register and/or Product Register) that allow to retrieve SoC product and
+revision information. If present, device nodes for these devices should
+be added.
+
+Required properties:
+ - compatible: Must be one of:
+ - "renesas,cccr" for the Common Chip Code Register,
+ - "renesas,prr" for the Product Register.
+ - reg: Base address and length of the register block.
+
+
+Examples
+--------
+
+ cccr: chipid@e600101c {
+ compatible = "renesas,cccr";
+ reg = <0xe600101c 4>;
+ };
+
+ prr: chipid@ff000044 {
+ compatible = "renesas,prr";
+ reg = <0 0xff000044 0 4>;
