Hi Greg,
Thank you for looking at this.

Yes, I observed the complexity.

But, we cannot put all _trip directly under ZoneX directory. We can remove the thermal_trip directory, and put sensorY_trip under /sys/class/thermal/zoneX/. But this sensorY_trip needs to be a directory which has four sysfs nodes named, active, passive, crit, hot.
Rui, What do you think about this ?
The only other way I see, is directly put sensorY_trip_[active/passive/hot/crit] which will create way too many nodes, under /sys/class/thermal/zoneX/.
Thanks, Durga
