 support

> No, sc8280xp and x1e80100 don't support it. So I didn't add the support for them.

Hm... From what I heard charge limiting works on some X1E laptops, e.g. the ThinkPad T14s on Windows using Lenovo Vantage.

Do you happen to know how that works? Is that some vendor specific solution? Or does it depend on the version of the battery management firmware? (AFAIK this is part of the adsp firmware?)

Thanks,
