I originally thought this was a nice way to handle embedded irqchips within the PCIe host, but it only really works by coincidence with the current kernel, and only as long as the hwirq number of the irqchip matches the integer representation of the irq line in the root bridge (which it does in the example above). For that driver we concluded that it would be less of a hack to have the irqchip as a child node of the PCIe host after all (just not with device_type="pci" of course), and that makes the translation work as expected.
