In exchange of acknowledgements I confirm that I understood the issue you are describing. What I still don't like is this band-aid:ish approach. What we really need is to replace of_node by fwnode in GPIO library once for all. But it can be done later after your simulation series (or before, i.o.w. independently), hence I propose to update TODO and do it separately. -- With Best Regards, Andy Shevchenko
