Rafael, Andy, Any ideas why fwnode_device_is_available() would return false for a built-in PCI device with a ACPI device entry? The only thing I see in the log is it looks like the parent PCI bridge/bus doesn't have ACPI device entry (based on "[ 0.913389] pci_bus 0000:07: No ACPI support"). For DT, if the parent doesn't have a node, then the child can't. Not sure on ACPI. Rob
