For me, 2 devices pointing to the same node seems implementation issue rather than fixing/ working around by extending DT bindings like this $subject patch is attempting. If you disagree with that and think 2 devices in the kernel shouldn't point to the same device tree node, then yes I see this is right approach to take. ATM I don't know which is correct and what are other developer's include DT maintainer opinion on this. I just didn't like the way Peng was trying to solve it with some block/allow list which wouldn't have fixed the issue or just created new ones. -- Regards, Sudeep
