| Description:	Sensor groups directory for POWER9 powernv servers
 | |
| 
 | |
| 		Each folder in this directory contains a sensor group
 | |
| 		which are classified based on type of the sensor
 | |
| 		like power, temperature, frequency, current, etc. They
 | |
| 		can also indicate the group of sensors belonging to
 | |
| 		different owners like CSM, Profiler, Job-Scheduler
 | |

| Description:	Sysfs file to clear the min-max of all the sensors
 | |
| 		belonging to the group.
 | |
| 
 | |
| 		Writing 1 to this file will clear the minimum and
 | |
| 		maximum values of all the sensors in the group.
 | |
| 		In POWER9, the min-max of a sensor is the historical minimum
 | |
| 		and maximum value of the sensor cached by OCC.
