No, as I pointed out before, the DT node comes in through
pci_scan_root_bus:
+static struct pci_bus __init *xilinx_pcie_scan_bus(int nr,
+ struct pci_sys_data *sys)
+{
+ struct xilinx_pcie_port *port = sys_to_pcie(sys);
+ struct pci_bus *bus;
+
+ if (port) {
+ port->root_busno = sys->busnr;
+ bus = pci_scan_root_bus(NULL, sys->busnr, &xilinx_pcie_ops,
^^^^^^
You can't pass NULL here and have DT work properly.
