The NXP pcf85063 supports two different xtal load capacitance - 7000fF (7pF) HW default, Linux driver default - 12500fF (12.5pF) Minimum power consumption To obtain a precise RTC the pcf85063 must be configured with the correct capacitance load of the xtal. Add a property to specify the xtal capacitance load. The default value matches that of the current Linux driver.
