Hi,
I also thought about it, then decided to focus on simply adding the new property first since I am not an expert in YAML.

I think it would be best to do it after this patch series. Keep in mind that the original intent of this patch series, and this new property, was to fix a regression related to the GPIOs, and I think that converting to YAML would simply delay and add much noise to the discussion at this point.

If someone wants to do it as a separate patch after this, fine. If not, I an willing to give it a go.

Hugo.
