Device Tree • Re: NVMe temp sensor - using hwmon for cooling an NVMe drive is non working

Maybe my way of thinking was too simple! When using 'cpu_thermal' as target in fragment3 that overlay works, using SoC temperature. Hence I simply followed the same approach for the NVMe temp sensor.
Or will it just work that way - by coincidence - because 'cpu_thermal' linked node exists somewhere?

Isn't NVMe drive temperature implemented in hwmon starting from Kernel 5.5 (CONFIG_NVME_HWMON)?

For an HDD which exposes a temperature (hddtemp) one would use 'drivetemp' label

Code:

cat /sys/class/hwmon/hwmon*/name

Code:

grep -l "drivetemp" /sys/class/hwmon/hwmon*/name/sys/class/hwmon/hwmon<x>/name
with hwmon<x> the HDD sensors temperature.
Or am I wrong starting from here?

In case of an NVMe there is no 'drivetemp' entry in hwmon, but the 'nvme' label.
