+Ralink Watchdog Timers
+
+Required properties :
+- compatible: must be "ralink,rt2880-wdt"
+- reg: physical base address of the controller and length of the register range
+
+Optional properties :
+- interrupt-parent: phandle to the INTC device node
+- interrupts: Specify the INTC interrupt number
+
+Example:
+
+ watchdog@120 {
+ compatible = "ralink,rt2880-wdt";
+ reg = <0x120 0x10>;
+
+ interrupt-parent = <&intc>;
+ interrupts = <1>;
