I understand, it's not your fault at all.

YES!!!!

Originally it was a "something that wasn't connected to a bus, but just
had memory-mapped i/o."  Like the PS2 keyboard controller.

Embedded systems got ahold of this and went to town, and made everything
a platform device because they could, and no one was paying attention.

Then OF came along and used it as well, and you know the rest...

I think we need to get the ACPI and OF people, and me, in a room
together at the kernel summit and not let us out until we have this all
worked out.
