Let me investigate a bit to see what's wrong. I stand corrected: it works perfectly. So: Tested-by: Andrea della Porta I think it should even be possible to tweak the static RPi5 DT in order to make it work dynamically with your patch. Can you please provide the relevant PCI DT nodes (from PCI controller to pci-ep-bus endpoint) from the output of: dtc -I fs -O dts /sys/firmware/devicetree/base/ taken on your reference board?
