+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>;
+	};
