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) 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 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 .../devicetree/bindings/misc/fsl,qoriq-mc.txt | 39 ++++++++ arch/arm64/boot/dts/freescale/fsl-ls208xa.dtsi | 6 +- drivers/bus/fsl-mc/fsl-mc-bus.c | 16 +++- drivers/iommu/arm-smmu.c | 7 ++ drivers/iommu/iommu.c | 21 +++++ drivers/iommu/of_iommu.c | 26 +++++- drivers/of/address.c | 102 +++++++++++++++++++++ drivers/of/irq.c | 7 +- drivers/pci/of.c | 101 -------------------- include/linux/fsl/mc.h | 8 ++ include/linux/iommu.h | 2 + include/linux/of_address.h | 11 +++ include/linux/of_pci.h | 10 -- 13 files changed, 234 insertions(+), 122 deletions(-) -- 1.9.1
