Thanks. I've sent a v4, but no changes to this patch.

I'm not sure what is the custom with xilinx dts changes. With the other 
platforms dts changes have always gone through a single tree, not via 
driver trees.

I don't have a preference either way, so if there's no clear rule here, 
I can take this one with the other patches.
