charset="utf-8" From: Stewart Hildebrand Handle phantom functions in iommu_add_dt_pci_sideband_ids(). Each phantom function will have a unique requestor ID (RID)/BDF. On ARM, we need to map/translate the RID/BDF to an AXI stream ID for each phantom function according to the pci-iommu device tree mapping [1]. The RID/BDF -> AXI stre= am ID mapping in DT could allow phantom devices (i.e. devices with phantom functi= ons) to use different AXI stream IDs based on the (phantom) function.
