+Device-Tree bindings for Renesas WDT reset functionality
+
+Required properties:
+ - compatible: must be one or more of the following:
+ - "renesas,r7s72100-reset" for the r7s72100 SoC
+ - "renesas,wdt-reset"
+ This is a fallback for the above renesas,*-reset entries
+
+ - reg: base address and length of the WDT register block
+
+Example node:
+ wdt: timer@fcfe0000 {
+ compatible = "renesas,r7s72100-reset", "renesas,wdt-reset";
+ reg = <0xfcfe0000 0x6>;
+ };
