I've not yet looked at plain Ethernet drivers. This pattern could also
exist there. And i wonder about other complex structures, i2c bus
multiplexors, you can have interrupt controllers as i2c devices,
etc. So the general case could exist in other places.
I haven't seen any generic issues like this reported so far. It's only
after adding phy-handle that we are hitting these issues with DSA
switches.
Can you run your parser over the 2250 DTB blobs and see how many
children have dependencies on a parent? That could give us an idea how
many moles need whacking. And maybe, where in the tree they are
hiding?
