You wrote that 6/7 depends on this. I prefer not to take DTS changes if
the corresponding user (driver) is still under discussion because the
bindings might change. I'll take it when bindings got acked or accepted.

Well, audio support in 4.9 is still not functional due to missing other
patches to ALSA SoC, so nothing will break as for now if we manage to get
this into v4.10.

BTW, the 6/7 is a quite reasonable ABI break, but for the sake of
documentation - why you did not continue with the patch for marking
bidings as experimental/under-development?

Because I had no time to list all breaks, what was requested by Rob.
