Of course it's all possible, but I think it would become unmaintainable in future without separate drivers. There is some extra freeze functionality and a watchdog warn interrupt: both do not exist in the DA9063. What I did say **one month ago** was the DA9062 watchdog driver does have some similarities with the DA9063 watchdog (https://lkml.org/lkml/2015/5/6/505). But I would prefer two drivers for watchdog in this case. When compared to the RTC and OnKey the watchdog is very different on the hardware side. Despite the appearance of some similarity, the watchdog is not a functional clone like the RTC and OnKey components. I would not like a combined watchdog driver because I think that the extra functions that the DA9062 contains would bloat out the DA9063 watchdog, and would make it difficult to test and to maintain for the future..
