Yes, it's made simple things easier, but note the problem I also pointed out towards the end of the email (I assume you stopped reading it towards the end?) DT also makes it much easier to make mistakes which take hours to find. DT has also made hard things much harder to solve - and because they're hard to solve people are hacking around the problem creating their own custom solutions, thereby making the problem much worse to solve in the future. That's a disease - "we must have DT and sod everything else" is a very bad thing to do. The bad news is, it *is* happening. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
