Well, there are some devices like that. But I think: * most devices aren't like that * most GPIO lines are more complicated than "just follows a register bit" * most devices that do have GPIO lines don't have very many and it's not very complicated to just implement them by open coding them * a special case facility that only gets used for the rare situation is going to make those devices harder to understand and maintain because they do things in a different way to everything else > Is there any chance I can convince you that this is useful and > get it merged? It doesn't seem very likely, I'm afraid. thanks -- PMM
