The agenda for such a day should probably be partially broken down per subsystem, yes, and it would make sense for people from the various areas to describe the kind of setup that they need to be able to define, similar to how you did in your writeup above. In some cases it would be a matter of in-person review/discussion/arguments of already proposed bindings, in other cases it would probably be a seeding discussion for upcoming bindings instead. Having the latter piggy-back on hearing what's discussed with the former category would likely be a good idea. -Olof -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
