There are also ath12k PCI devices which don't need DT at all. I don't know if that should be reflected in the bindings doc but I want to point out this.

What's wrong with having the author of the bindings in the Cc list? If you want follow the ath12k development and review patches then you can join the ath12k list. I'm not fond of having too many maintainers, it's not really helping anything and just extra work to periodically cleanup the silent maintainers. I would ask the opposite question: why add you as the maintainer? There's not even a single ath12k patch from you, nor I haven't seen you doing any patch review or otherwise helping others related to ath12k. Don't get me wrong, I value the work you do with this important powerseq feature and hopefully we get it into the tree soon. But I don't see adding you as a maintainer at this point.

But I don't see > adding you as a maintainer at this point. This is not a maintainer of driver. This is maintainer of bindings, so someone who has hardware, datasheets, knowledge and/or interest in keeping the bindings accurate. All your arguments above suggest you talk about the driver. This is not the point here. Best regards, Krzysztof

I only want to clarify the purpose of the binding maintainer. Best regards, Krzysztof

Speaking just for myself, I know Bartosz is far more capable in this regard than I am, so I'd expect him to be listed as a maintainer before me. /jeff
