Reading the C620 datasheet I see this interface also allows other
commands (wake up, watchdog feeding, reboot etc.) and reading statuses
(e.g Intruder Detect, POWER_OK_BAD).

I think if there's any plan to use anything other but RTC via this
interface then the driver should be registered as an MFD.
