Yeah. I've been thinking about it and I agree now. I'll erase the handler.

Well, the short answer to this is, it's not the same. I was just in the process of
replying to that other thread. The OnKey and RTC are functionally similar, so I
am going to look at integrating the two drivers in some future patch sets, but
the watchdog is definitely not based upon DA9063.
I did mention this in a previous thread:
