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. greg "platform devices are dead, long live the platform device" k-h
