What I meant was that at the point when arch/arm/boot/dts/*
is (if ever) removed from the kernel tree and into its own git, so that
the standardization of bindings is decoupled from the Linux kernel
tree, from that point it is no longer possible to alter the bindings
and the code in sync, so at that point the bindings need to be
frozen and all subsequent work will need to gear down and
work on bindings before deployment.

That said, this does not at all solve the problem of already-deployed
device trees using old bindings...

I'm +1 on this. But I have learned that I have had to strike a
compromise with people who want to forge ahead. They see things
in the other way: perpetual committee discussions and no code
nor device trees being deployed... :-)
