Why? Your commit msg must explain this. You break users of this DTS on
older kernels and also this makes it impossible to apply via different
branches in the same cycle. All this needs explanation and proper
justification. Your message tells here nothing, because "what" is quite
obvious.

That's breaking users of this DTS (old kernel, out of tree, other
projects) for no real reasons without explanation.
