I am a bit surprised you don't rework struct dev. As of_node is now redundant
with fwnode.
I agree that this will eventually be removed. I have kept this in now just to
maintain compatibility
(compilation and otherwise) with smmuv2 driver. I will add a comment to
indicate this. So that it can
be easily identified and remove when we do a final cleanup. Can I prefix the
comment with with XEN:TODO:?
A TODO would be nice, but who is going to do the rework?
Cheers,
