Yeah. I've been thinking about it and I agree now. I'll erase the handler. > On a separate note, there was a comment stating that the da9062 watchdog > is identical to the da9063 watchdog. If so, why can't you just use the da9063 > watchdog driver ? 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.
