    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-decoder" instead. And remove 
"0x" from the address part of the node name please.
