Can be added as a Datasheet tag here (and be spread by `b4` to all patches in
the series, which I think is fine).

Can you split the first patch to be based on the features implemented?
Something like

- patch 0: DT binding
- patch 1: very basic (but working) driver
- patch 2...n: Features 1...(n-1)
