Current:
RTC alarm flags are getting reset during the initialization of the RTC which might be good for many use cases.
Suggested:
Allow to define that behavior in the device tree or with KConfig.
Why?
I have a use case where the RTC is waking up the MCU and I would like to understand if the RTC was waking the MCU up or if there was another reason. The only way with the hardware at hand is to read the alarm flag but they get reset.
