Oh, I guess I could not explain myself :). I did not meant breaking the system (I'm aware of the dummy regulator) but I meant exactly what you mention above about dtbs_check. Like, if someone already validated a devicetree against the current bindings, that same devicetree will fail to validate now right? And I had the idea that we should not allow that... If not the case, I'm perfectly fine in making the supply required. - Nuno Sá >
