[RFC PATCH 0/6] iommu/arm-smmu: Add support for DMA domains and instruction fetch

[Anup Patel]

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.
