+STM32 Independent WatchDoG (IWDG)
+---------------------------------
+
+Required properties:
+- compatible: "st,stm32-iwdg"
+- reg: physical base address and length of the registers set for the device
+- clocks: must contain a single entry describing the clock input
+
+Example:
+
+iwdg@40003000 {
+ compatible = "st,stm32-iwdg";
+ reg = <0x40003000 0x400>;
+ clocks = <&clk_lsi>;
+};
