Why is CONFIG_WDT_STM32MP enabled here , is this the ARM SMC watchdog
driver ?
This is aligned with stm32mp15 config, and no, this one is the STM32
IWDG driver.
I'll check that with Patrick (who originally wrote the patch), as it
seems that this flag could be removed.
I agree with Marek.
Today CONFIG_WDT_STM32MP is not really needed as only arm_wdt is
activated in STM32MP13 device tree for ST boards
Make sure you double-check the stm32mp13xx dhcor too.
If the WDT is supposed to be activated here, it has to be documented in
commit message too .
