+- reg             : Offset and length of the register set for the device.
+- interrupts      : Contain the timer interrupt with flags for
+                    falling edge.
+
+Optional:
+- clocks          : phandle of watchdog timer reference clock.

+Example:
+
+watchdog0: watchdog at f0008000 {
+	compatible = "nuvoton,npcm750-wdt";
+	interrupts = <GIC_SPI 47 IRQ_TYPE_LEVEL_HIGH>;
