Right and I don't advocate changing existing perfectly working platform drivers, I think having wrappers to create them is fine. In fact, I've been thinking for a long time about doing something like that: Have those wrappers be registered via a standard OF set of match strings for bus types and device types. Then we can have a single loop that walks the tree, invoke those "constructors" that return a struct device * (whatever the device type that was actually created, could have been platform_device, pci_dev, amba_device, etc...). It also passes them the parent device * That way, all devices are instanciated from the DT -and- the topology in sysfs preserves the topology in the device-tree (ie, parent/child relationships are preserved).
