What format is "<num>" in?

If that's the only possible value, this property is unnecessary,
no?  It probably would make sense to make this optional (and default
to "host") anyway.

Why is this linux-specific?

Similar here, except this one is never a GPIO controller.
If the point to have #a = #s = 0 is to not have a unit-address
in the child nodes: you should do that simply by not specifying
a "reg" in the child nodes.

This one is so full of "linux," stuff that I won't review it --
I wouldn't know where to start, sorry.
