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
