Robert: Is there a way to make the external DS3231 the wakeup device? Just like in this RaspPi thread, I want to set the alarm and use the INT pin on the clock chip to activate something.

I’ve already made the INT pin work using Adafruit's python libraries for the DS3231, but I’d like to use the linux tools if possible - then I can also use the clock to set the system time. Of course if the device tree is using the clock, the python libraries can’t get to it.
