One of the real problems right now is the lack of DT reviewers and general reviewer fatigue. In particular, many of the proposed bindings tend to have the same issues (focusing too much on how the platform_data is structured today and not on what the hardware actually is), and a few other similar things. Based on that I don't think it's a better solution to have the same few people walk from room to room to cover the same thing multiple times. No one has to sit there the whole day and listen on it all, but for those who are genuinely interested in how other subsystems will handle these bindings, I think it would be very useful to learn from how they made their decisions. Don't work in a vacuum, etc. So, I'd like to formally propose this as a mini-summit or workshop or whatever you might want to call it. I can help organize it together with Rob and Grant if needed (especially since Grant has a lot of other things going on at the moment). If there's insufficent interest to do this as a separate event we can try to accomodate for it as part of the ARM mini-summit, but squeezing all of that in with the rest of the ARM activities in one day will be hard. -Olof -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
