Thanks for the helpful suggestions, that makes sense.

What I keep forgetting in my little arm-imx6 world, is that devicetrees
aren't in-kernel apis, but that they have out-of-kernel
dependencies. It makes more sense to to see them as userspace
apis, albeit directed at firmware/bootloaders, right?

So if bootloaders were as varied/uncontrollable as userspace,
then deprecated properties would have to be supported forever...
