In the last revision, I asked you to provide changelog between revisions,
*please* do this. You received review on the last version and a bunch of the
feedback hasn't been taken into account with no explanation as to why. Please go
back to the last version, read the reviews that people were generous enough to
give and either fix the code or explain why you're not.

Archit asked you not to do this in the previous review.
I've replied with some more details to the patch which adds this in the DT
binding doc.
Thanks,
