I understand, it's a thin line across which I pushed ESM into hwmon; my 
reasoning was ESM also actively looks for signals that it aggregates, 
and is overall monitoring the device health. But if there was an option, 
in order of fitting: fault/ > misc/ > hwmon/

Using misc/ was questioned in an earlier review; and fault/ is not yet 
created and I did not think there were enough instances to back me up on 
creating a new dt-bindings dir

To come to a common solution, let us keep this binding in misc/ along 
with other fault detection mechanisms existing and take it up as a 
follow up action to create a fault/ ?
