I don't understand your comment. This patch modifies the binding. The link you 
provide is from an older version of the series (which is called v2 as well...)

So repeating myself: if you are updating the binding descritpion you will have 
to update the dtsi as well as otherwise the binding and the dtsi are out of sync.
