Hello Falviu, thank you for your patch.
Should we not add a reference to hwmon-common.yaml (with
unevelautedProperties instead of additionalProperties), as label is
defined there? I believe that Krzysztof Kozlowski did something similar
for the shunt-resistor-micro-ohms property. Could we follow suit here?
I am also not a big fan of a name like "somelabel", and a more
meaningful name from a "real" example would look better. I know that
some examples have already used "somelabel" as an example, but others
have used more meaningful names too.
Best regards,
Javier Carrasco
