Can't this patch then simply go into your for-next branch then?
The split is most times binding goes through the driver-tree
(or Rob's dt tree) and the dts patch through an arch or soc tree.
But in general once a maintainer accepts the binding it is ok
to also apply the dts patch for the same cycle (aka merge window)
the binding will be in.
