Please don't use underscores in devicetree for anything that's not a phandle.

Apart from the underscore being invalid, across the kernel, you can find many
instances of opp tables, containing names related to the frequencies, so, for
consistency (this is not a rule!), perhaps it would be a good idea to do so.

This one is fine instead :))
