Please explain in the commit message why you change this binding and why 
this is not problematic. Either in this patch or add a new one.

For convenience for the device-tree maintainer, add the binding patches 
at the beginning of your patch list. It makes their life easier and a 
review faster, a clear win-win situation :)

Thanks,
Matthias
