The first two patches in this series add support for this output clock. The third patch of the series disables the 100th counter available in the PCF2131. This counter is enabled by default in the hardware but 100th seconds are not used by the RTC subsystem. Fully disabling it allows to save energy when the RTC is powered by its battery without any functional changes.
