+Renesas Product Register
+
+Most Renesas ARM SoCs have a Product Register or Boundary Scan ID 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 one of:
+ "renesas,prr"
+ "renesas,bsid"
+ - reg: Base address and length of the register block.
+
+
+Examples
+--------
+
+ prr: chipid@ff000044 {
+ compatible = "renesas,prr";
+ reg = <0 0xff000044 0 4>;
+ };
