I haven't given review remarks on public list but had few internal
review discussions with you. So just in case you need some
additional review/ack tags, feel free to include mine.

Acked-by: Santosh Shilimkar <santosh.shilimkar@xxxxxx>

Once the driver changes gets merged by Bjorn, I can they
merge the DTS related changes via my tree.

Thanks for all the work Murali !!

Santosh
