This patchset from Vadim includes various enhancements to thermal and
hwmon code in mlxsw.
Patch #1 adds a thermal zone for each inter-connect device (gearbox).
These devices are present in SN3800 systems and code to expose their
temperature via hwmon was added in commit 2e265a8b6c09 ("mlxsw: core:
Extend hwmon interface with inter-connect temperature attributes").
Currently, there are multiple thermal zones in mlxsw and only a few
cooling devices. Patch #2 detects the hottest thermal zone and the
cooling devices are switched to follow its trends. RFC was sent last
month [1].
Patch #3 allows to read and report negative temperature of the sensors
mlxsw exposes via hwmon and thermal subsystems.
