I have a driver that knows the IO port it wants. It's not set up by a
parent bus, so I can't use bus_set_resource(). This call returns NULL.
Any idea how to debug why newbus is rejecting this request? The io port
is not in use and the rid is unique.
bus_alloc_resource(dev, SYS_RES_IOPORT, rid, 0x101c, 0x101c, 1,
RF_ACTIVE);
Thanks,
-Nate
