Are you starting up PCI? For example, with: ret = uclass_get_device(UCLASS_PCI, 0, &bus); If you are, then it should scan the bus and find and bind all the devices, in pci_bind_bus_devices(). You can add DEBUG to the very top of that file to see. But if you know the device is there, you may as well create a device tree-node for it. See chromebook_link.dts 'pci' node for an example. Then you can request the device directly, and PCI will be started up automatically.
