[PATCH 0/7 v6] Support for fsl-mc bus and its devices in SMMU

From: Nipun Gupta
Date: Mon Jul 09 2018 - 07:19:12 EST


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

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
