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. -- Be free, use free (http://www.gnu.org/philosophy/free-sw.html) software! mailto:fercerpav@...il.com
