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.

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?

Best regards,
Krzysztof
