+* Renesas R-Car Thermal

+Required properties:
+- compatible           : "renesas,rcar-thermal"
+- reg                  : Address range of the thermal registers.
+                         The 1st reg will be recognized as common register
+                         if it has "interrupts".
+
+Option properties:
+
+- interrupts           : use interrupt

+Example (non interrupt support):
+
