This series introduces SMMU handling for PCIe passthrough on ARM. These patches
are independent from (and don't depend on) the vPCI reference counting/locking
work in progress, and should be able to be upstreamed independently.

v3->v4:
* split a change from ("xen/arm: Move is_protected flag to struct device") into
  a new separate patch
* see individual patches for further details

v2->v3:
* drop "pci/arm: Use iommu_add_dt_pci_device()"
* drop "RFC: pci/arm: don't do iommu call for phantom functions"
* move invocation of sideband ID mapping function to add_device()
  platform_ops/iommu_ops hook

v1->v2:
* phantom device handling
* shuffle around iommu_add_dt_pci_device()

Oleksandr Andrushchenko (1):
  xen/arm: smmuv2: Add PCI devices support for SMMUv2

Oleksandr Tyshchenko (4):
  xen/arm: Improve readability of check for registered devices
  xen/arm: Move is_protected flag to struct device
  iommu/arm: Add iommu_dt_xlate()
  iommu/arm: Introduce iommu_add_dt_pci_sideband_ids API

Rahul Singh (1):
  xen/arm: smmuv3: Add PCI devices support for SMMUv3

Stewart Hildebrand (1):
  iommu/arm: iommu_add_dt_pci_sideband_ids phantom handling
