OK, I think this is the disconnect here.

No matter what order Jimmy's patches land in, it won't be bisectable
from the standpoint of "make dtbs_check". This is what I've been
trying to say.

* If the bindings land first then the device tree won't have sku6 and
will fail "make dtbs_check"

* If the dts lands first then the bindings won't have sku6 and will
fail "make dtbs_check".

Am I missing something?

So when you said "I don't think anyone said that bindings patches must
be separate from DTS" and that you cared about "make dtbs_check" being
bisectable that you were saying you wanted these squashed into one
patch. I guess that's not the case.
