I also asked to check other exposed properties and to provide a dump of the power-supply uevent in commit message or cover letter to verify chip works as expected. I cannot see the dump and you are exposing at least one property that always reports -ENODATA. I intentionally will not point out the exact property, so that you have to properly test your patch before submitting.

Thanks,
