Subject: [PATCH 0/4] Add system mmu support for Armada-806

From: Hanna Hawa <hannah@...vell.com>

This series add support for IOMMU for AP806, including workaround
for accessing ARM SMMU 64bit registers.
AP-806 can't access SMMU registers with 64bit width, this patches split
the readq/writeq for 32bit access, due to erratanum #582743.

Hanna Hawa (4):
  iommu/arm-smmu: introduce wrapper for writeq/readq
  iommu/arm-smmu: Workaround for Marvell Armada-AP806 SoC erratum
    #582743
  dt-bindings: iommu/arm,smmu: add compatible string for Marvell
  arm64: dts: marvell: add smmu node for Armada-AP806
