+Synopsys Designware Watchdog Timer
+
+Required Properties:
+
+- compatible : Should contain "snps,dw-wdt"
+- reg : Base address and size of the watchdog timer registers.
+- clocks : phandle + clock-specifier for the clock that drives the
+ watchdog timer.
+
+Optional Properties:
+
+- interrupts : The interrupt used for the watchdog timeout warning.
+
+Example:
+
+ watchdog0: wd@ffd02000 {
+ compatible = "snps,dw-wdt";
+ reg = <0xffd02000 0x1000>;
+ interrupts = <0 171 4>;
+ clocks = <&per_base_clk>;
+ };

+MOXA ART Watchdog timer
+
+Required properties:
+
+- compatible : Must be "moxa,moxart-watchdog"

+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
