-STM32 Independent WatchDoG (IWDG)
----------------------------------
-
-Required properties:
-- compatible: Should be either:
- - "st,stm32-iwdg"
- - "st,stm32mp1-iwdg"
-- reg: Physical base address and length of the registers set for the device
-- clocks: Reference to the clock entry lsi. Additional pclk clock entry
- is required only for st,stm32mp1-iwdg.
-- clock-names: Name of the clocks used.
- "lsi" for st,stm32-iwdg
- "lsi", "pclk" for st,stm32mp1-iwdg
-
-Optional Properties:
-- timeout-sec: Watchdog timeout value in seconds.
-
-Example:
-
-iwdg: watchdog@40003000 {
- compatible = "st,stm32-iwdg";
- reg = <0x40003000 0x400>;
- clocks = <&clk_lsi>;
- clock-names = "lsi";
- timeout-sec = <32>;
-};
