Can we expand the BUS_ADD_* concept to other devices instead of just
acpi_device?

aka we should let struct device has this add_type field.

Having done that in ACPI to cover our use case here, we can try to move it
into struct device if there are use cases beyond ACPI that can't be covered
by using deferred driver probing.

pci device for hotplug have same problem. need to delay driver attach
for them too.

OK, I'll take a look.  Any pointers to speed that up?

also BUS_ADD_MATCH and BUS_ADD_START are duplicated.

Not at the moment, they do different things as code goes.

old add are separated to adding all devices to tree and then matching
work to load the drivers.

so _START is not needed anymore, only user.start in pci_root driver
should be removed.
code in .start could be moved .add without problem.

Yes, I'm going to do that as the next step.  I didn't want this particular
patchset to grow too big.  I'll post another one on top of it if people
don't have problems with this one.

Thanks,
Rafael
