Subject: [PATCH 0/7 v7] 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 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, 6)
  - Updates the fsl-mc device node with iommu/dma related changes (patch 7)

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

Changes in v3:
  - move of_map_rid in drivers/of/address.c

Changes in v4:
  - move of_map_rid in drivers/of/base.c

Changes in v5:
  - break patch 5 in two separate patches (now patch 5/7 and patch 6/7)
  - add changelog text in patch 3/7 and patch 5/7
  - typo fix

Changes in v6:
  - Updated fsl_mc_device_group() API to be more rational
  - Added dma-coherent property in the LS2 smmu device node
  - Minor fixes in the device-tree documentation

Changes in v7:
  - Rebased over linux 4.19

Nipun Gupta (7):
  Documentation: fsl-mc: add iommu-map device-tree binding for fsl-mc
    bus
  iommu/of: make of_pci_map_rid() available for other devices too
  iommu/of: support iommu configuration for fsl-mc devices
  iommu/arm-smmu: Add support for the fsl-mc bus
  bus: fsl-mc: support dma configure for devices on fsl-mc bus
  bus: fsl-mc: set coherent dma mask for devices on fsl-mc bus
  arm64: dts: ls208xa: comply with the iommu map binding for fsl_mc
