Subject: [PATCH 0/6] Support for fsl-mc bus and its devices in SMMU

This patchset defines IOMMU DT binding for fsl-mc bus and adds
support in SMMU for fsl-mc bus.

These patches
  - Define the new property 'iommu-parent' for fsl-mc bus (patch 1)
  - Integrates the fsl-mc bus with the SMMU using this
    IOMMU binding (patch 2,3)
  - Adds the dma-mapping support for fsl-mc bus (patch 4,5)
  - Updates the fsl-mc device node with iommu/dma related changes

This patchset is based on staging-testing tree where fsl-mc bus is out
from staging

This patchset is dependent on patch https://patchwork.kernel.org/patch/10207507/;
otherwise DPAA2 Ethernet driver functionality will break.
