In practice I bet no one uses Linux 5.0's i.MX8M device trees since they lack too much support. It's so basic it's not useful. You'd still run your existing non-mainline bindings until it is. Thus I would argue changing the ABI right now would be the only chance there is. If you think that chance is gone, then I guess the reasonable thing is to keep the numbers and only move those (to the end) which overlap. Or put them into that erreneous number gap. Patrick
