But it looks like > inconsistency to me. Right. So is there inconsistency right now ? Yes, there is. The important question we need to answer is where do we want to see all these drivers (specially new ones) in the future. What's the right thing to do eventually ? Hardcode stuff ? Or Move it to DT ? The answer is DT for me, so the code can be generic enough to be reused. This is just one step in the right direction I guess. Eventually the drivers must get simplified, which they are I guess. -- viresh
