This patchset adds following to SMMUv1/SMMUv2 driver:
1. Support for domain type IOMMU_DOMAIN_DMA
2. Allow privilege instruction fetchs from MMU masters by having
a DT option to treat instruction fetch as data read

The patchset is based on '4.5-rc1' tag of linux mainline tree
and is available in smmu_v1 branch of
https://github.com/Broadcom/arm64-linux.git

All patches have been tested on Broadcom SoCs having SMMU-500.

  iommu/arm-smmu: Invoke DT probe from arm_smmu_of_setup()
  of: iommu: Increment DT node refcount in of_iommu_set_ops()
  iommu/arm-smmu: Add support for IOMMU_DOMAIN_DMA in SMMUv1/SMMUv2
    driver
  iommu/arm-smmu: Option to treat instruction fetch as data read for
    SMMUv2
  iommu/arm-smmu: Update bindings document for smmu-inst-as-data DT
    option
