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



Optional Properties:

- timeout-sec: Watchdog timeout value in seconds.



Example:



iwdg: watchdog@40003000 {

	compatible = "st,stm32-iwdg";

	reg = <0x40003000 0x400>;

	clocks = <&clk_lsi>;

	timeout-sec = <32>;

};
