I'll throw in the caveat that I'm not 100% sure we're that stable yet,
but it certainly seems like it, at least for the overall portion where
you might really have incompatible trees.  More or less complete (now
every device is described!) dts should be interchangable to the kernel
for the custom board X is just a little different from ref board Y
issues (and now, in theory, the Just Like A Sandpoint board, with a
correct dts will boot the 'sandpoint' kernel). 

The sandpoint (as far as I know) does not have a stable DTS. So in this
case including the DTS in the kernel would reduce confusion. The same
could be said for other boards where the DTS needed to be changed for
the IRQ rework. The old DTS will no longer boot the new kernels. I'm not
sure how much longer we will run into this problem though.

Yes, as I said, I'm not totally sure we're at the stable point right
now, but I think that we are.  I'll add that maybe we need to think
about API changes and DTS format versions.  To quote from my post..

X bugs) or a change that requires a dts version bump.

Now it sounds like the IRQ thing was an "Oops, we should have changed
the dts version" and bailed, noting what is wrong with the dts.
