Subject: [PATCH 0/7 v5] 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.

The patch series is based on top of dma-mapping tree (for-next branch):
http://git.infradead.org/users/hch/dma-mapping.git

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

Nipun Gupta (7):
  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: 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
