Some platform devices appear as PCI but are
actually on the AMBA bus, and they need fixup in
drivers/pci/quirks.c handling iommu_fwnode.
So calling pci_fixup_final after iommu_fwnode is allocated.
For example:
Hisilicon platform device need fixup in
drivers/pci/quirks.c
+static void quirk_huawei_pcie_sva(struct pci_dev *pdev)
+{
+ struct iommu_fwspec *fwspec;
+
+ pdev->eetlp_prefix_path = 1;
+ fwspec = dev_iommu_fwspec_get(&pdev->dev);
+ if (fwspec)
+ fwspec->can_stall = 1;
+}
+
+DECLARE_PCI_FIXUP_FINAL(PCI_VENDOR_ID_HUAWEI, 0xa250, quirk_huawei_pcie_sva);
+DECLARE_PCI_FIXUP_FINAL(PCI_VENDOR_ID_HUAWEI, 0xa251, quirk_huawei_pcie_sva);

iommu/of: Let pci_fixup_final access iommu_fwnode
ACPI/IORT: Let pci_fixup_final access iommu_fwnode
