Thank you for your patch. There is something to discuss/improve.

It does not look like you tested the bindings, at least after quick
look. Please run `make dt_binding_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).
Maybe you need to update your dtschema and yamllint.

These are "properties"

1. Missing vendor prefix (does not look like generic property)
2. -microvolt

And then enum is for 40, 80, 160 and 320.

I am sure hwmon has some property for this. Are you sure it is called
"average"?
