Is there an example of an rtc driver implementing this? For the rv3029 it's more than just enabling it. It also has a bunch of charging resistors to choose from. > I'm not sure yet about the temperature compensation.

The rv3029 does the compensation internally. It just needs to be enabled via a bit in its EEPROM. We could probably always set that bit though. I'm not sure whether there is a case where one would not want that. -- Michael -- -- You received this message because you are subscribed to "rtc-linux".
