I just enabled the following new config parameters:
++CONFIG_INPUT_PCF50633_PMU=m
++CONFIG_CHARGER_PCF50633=m
++CONFIG_MFD_PCF50633=m
++CONFIG_PCF50633_ADC=m
++CONFIG_PCF50633_GPIO=m
++CONFIG_REGULATOR_PCF50633=m
++CONFIG_RTC_DRV_PCF50633=m
and then the build/installation failed with the following symbol errors:
