Kernel policy has always been that just because some vendor has deployed an interface doesn't mean we care one iota about it or consider it an argument for the solution. In some cases in fact it bcomes the working demo of why it was a bad idea. > But there are a huge number of users of platform_data in mainline > already we can agree.

Ultimately that will probably be worth doing once we have some kind of meaningful model. We've actually been slowly beating platform devices into making more use of the resource data it does have when possible, and we have various parsers between platform data and device specific platform data structs that are horrible glue-together jobs that it would be nice to stomp on. > I think the first additional effort needs to start at home on that one > and think through Device Tree and kernel policy on interoperation with > existing driver implementations using platform_data.

Things like interface names for example shouldn't be kernel mangled on the whim of random board vendors. They follow a unified behaviour *across* platforms, which is what matters most in the bigger picture. Other stuff is to all intents and purposes sometimes hard coded into drivers because while they are USB drivers they are checking specific vendor id fields and changing behaviour on them. In some cases those vendor id fields are actually a specific hardwired device.
