There is no OF binding, so no.

It's better to use real device names, just like everyone
else.

More than 32 bit?

Not required, depends on the interrupt tree of the system.

No.  The format of an "interrupts" entry is defined by
the interrupt domain this device sits in, not by the
device itself.

That's to be defined in the binding for your specific device,
not in a more generic rapidio binding.

You want a #size-cells as well.

Hope this helps,
