Having written/applied a significant portion of the arm devicetree files for several SoCs over the past couple of years, I share your concern. The reason I bring this up is because I keep seeing the little churn here and there because we _can_. I find it very similar to a teenager reaching adulthood. At a certain point, the parents have to say "Get out, get a job, get your own place." It's hard for all parties involved, but it's the best thing for the young adult in the long run. There's no substitute for living on your own and paying bills. I think the long term health of the devicetree would benefit greatly from being more detached than it currently is. It would force everyone to "Pay the bills". The time might not be right now, and it probably will take one of the more gradual forms Olof suggested. But I think it should happen at some point to help it grow up. And we still have the short term problem of facilitating other projects use of the devicetree. Which can only make it more robust and accepted by default. thx, Jason. -- To unsubscribe from this list: send the line "unsubscribe devicetree-spec" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
