Hello Grant,

I made some progress in this area, but I have now hit a problem I do not
know how to solve.
Taking code from the iseries/vio.c files I am able to add properties with
add_string_property and add_raw_property. 
The problem I have is adding properties like

    reg = <0x2520 0x20>

I know how to add a property

   reg = <0x2520>

but I do not know what data structure to pass to add_raw_property to add
two numbers there.

Kind regards,
Michael
