DT has many benefits. It would be great to leverage them as long as it
doesn't interfere with the rate of change and willingness to evolve code
that's always been the strength of the kernel process. That strength is
too valuable to trade away for the "DT as ABI" vision.

I agree with this, and have posted similar things before.

The question I asked last time this came up, which was left unaswered:

 Who does this stable DT ABI vision benifit, and how much is that
 benifit worth?

You might add: Who does the DT restriction to "hardware description only"
(ie it must not describe what the system is supposed to do with the hardware)
benefit, and how much is that benefit (or restriction) worth ?
