Yes, I merge a lot of shared branches with dt-binding changes into the
soc/dt branch, and I wasn't aware of a policy against that, certainly did
not enforce it.

I generally object to changes touching drivers/* or anything else besides
arch/*/boot/dts, Documentation/devicetree/bindings/ and include/dt-bindings
in the dt branches, but I have made expections in the past when there
was a particular important reason.
