interested in seeing what changes will need to be done for Xen IO. I

about the interfaces (or API's ) which drivers need to use. It would
be great if you could point me to the document or a link to a similar
kind of code which has done the same.

If this is a device that is not "virtualization aware", all you need
to do is have a working Linux driver in the Linux tree. Then simply
recompiling that tree for the Xen subarch should work. If your device
is virtualization aware, there's plenty that you could do, but there's
no one way of doing things yet. If that's the case, your best bet is
to describe what your device can do, and then we can talk about how to
best utilize it under Xen.
