Ok, so I'd suggest doing something like: - pci is below the corresponding atom node - isa is a child of pci The later is a useful representation even if it doesn't correspond to reality. From an address representation perspective, ISA can be considered somewhat as a substractive decoding child of PCI (again even if that's not 100% true), which simplifies the representation in the device-tree a bit, and allows to still have things like VGA devices on the PCI segment that decode IO ports in the ISA range.
