      4Description:	Sensor groups directory for POWER9 powernv servers
      5
      6		Each folder in this directory contains a sensor group
      7		which are classified based on type of the sensor
      8		like power, temperature, frequency, current, etc. They

     18		Writing 1 to this file will clear the minimum and
     19		maximum values of all the sensors in the group.
     20		In POWER9, the min-max of a sensor is the historical minimum
     21		and maximum value of the sensor cached by OCC.
