---------------------------------
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
+- 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.
