Enable an external RTC on I2C3

Discussion created by Vincent Chou on May 23, 2012

Hi! All,

I would like to know the procedure to enable an external RTC on I2C3 bus, say BQ23000, on QSB because we tried to add the circuitry on QSB and add the device driver on RTC for BQ23K and disable other RTC on QSB in LTIB but found out the driver does not work.  What did I do wrong in this case?  Is there a description for me to follow in order to enable an external RTC?  Thanks beforehand!
