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

This patch series is dependent on patset:
https://patchwork.kernel.org/patch/10317337/

These patches
  - Define property 'iommu-map' for fsl-mc bus (patch 1)
  - Integrates the fsl-mc bus with the SMMU using this
    IOMMU binding (patch 2,3,4)
  - Adds the dma configuration support for fsl-mc bus (patch 5)
  - Updates the fsl-mc device node with iommu/dma related changes (patch6)

Nipun Gupta (6):
  Docs: dt: add fsl-mc iommu-map device-tree binding
  iommu: of: make of_pci_map_rid() available for other devices too
  iommu: support iommu configuration for fsl-mc devices
  iommu: arm-smmu: Add support for the fsl-mc bus
  bus: fsl-mc: supoprt dma configure for devices on fsl-mc bus
  arm64: dts: ls208xa: comply with the iommu map binding for fsl_mc

Changes in v2:
  - use iommu-map property for fsl-mc bus
  - rebase over patchset https://patchwork.kernel.org/patch/10317337/
    and make corresponding changes for dma configuration of devices on
    fsl-mc bus
