Possibly to Rafael as well, he did a very intersting rework on device dependencies with device links. While in general I agree that this diets down a lot of duplicate code that we have done the same way over and over, there is the issue that we don't want any drivers to do this mockery and instead use deferred probe and ultimately just probe in the right order. I think device links were supposed to fix this up, but it indeed assumes that you know of these dependencies before you start probing the first driver, and often you do not, unless the hardware description explicitly encodes that. And that is one big problem. If we should do this, device core changes must be merged or explicitly ACKed first. Yours, Linus Walleij
