Good. Than me or federico will submit a proposal.

I don't think there are many pci bridges around, but platform drivers
exists just for that reason: to be instantiated when you know how the
wiring ("platform") details.  I.e., somebody registers the platform
device associated to the driver.

Sometimes the platform device is compiled in, sometimes it comes from
the device tree. I think it can come from PCI as well.
