    This patch should have been preceded by the VIN driver patch and bindings 
description, don't you think?

    ePAPR standard [1] tells us that:

The name of a node should be somewhat generic, reflecting the function of the 
device and not its precise programming model.

    So, I would suggest something like "video". And remove "0x" from the 
address part of the node name please.

WBR, Sergei
