2020-04-01powerpc/powernv: Add documentation for the opal sensor_groups sysfs interfacesShilpasri G Bhat1-0/+21
Commit bf9571550f52 ("powerpc/powernv: Add support to clear sensor groups data") added a mechanism to clear sensor-group data via a sysfs interface. However, the ABI for that interface has not been documented. This patch documents the ABI for the sysfs interface for sensor-groups and clearing the sensor-groups.
