+* 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):
+
+thermal@e61f0100 {
+ compatible = "renesas,rcar-thermal";
+ reg = <0xe61f0100 0x38>;
+};
+
+Example (interrupt support):

+ reg = <0xe61f0000 0x14
+ 0xe61f0100 0x38
+ 0xe61f0200 0x38
+ 0xe61f0300 0x38>;
