Yes, how many times do I have to keep saying this?
The platform bus should ONLY be used for devices that are actually
platform devices and can not be discovered any other way and are not on
any other type of bus.
If you try to add platform devices for a PCI device, I am going to
continue to complain. I keep saying this and am getting tired.
Now yes, MFD does do "fun" things here, and that should probably be
fixed up one of these days. But I still don't see why a real bus would
not work for you.
