Rob, I've been wondering about patch application with these DT bindings.
In the past I've preferred to apply these along with the driver changes
that implement the bindings. I realize now that that's perhaps a bit
naive because we've had cases where the driver doesn't fully implement
everything in the binding as well as cases where the bindings are
upstreamed without the driver necessarily being upstreamed at the same
time.

So I'm thinking that it makes more sense to apply the DT bindings to the
same tree as the DT changes that add corresponding DT nodes. This would
also get rid of the (usually temporary) inconsistencies when running the
DT validation (and even just something like checkpatch) on a DT tree
that doesn't have corresponding DT bindings.

Do you have any strong preference on this?
