[PATCH v1.5 0/6] R-Car DU: Fix IOMMU operation when connected to VSP

[Ulrich Hecht]

Hi!

This is a slightly updated version of Laurent's series that adds the fix
suggested by Magnus Damm and connects the FCP devices on M3-W to their
IPMMU. It also drops the patches that have already been picked up in the
media tree.

With this series and an assortment of patches from the renesas-drivers tree (
    iommu/ipmmu-vmsa: Remove platform data handling
    iommu/ipmmu-vmsa: Rework interrupt code and use bitmap for context
    iommu/ipmmu-vmsa: Break out utlb parsing code
    iommu/ipmmu-vmsa: Break out domain allocation code
    iommu/ipmmu-vmsa: Add new IOMMU_DOMAIN_DMA ops
    iommu/ipmmu-vmsa: ARM and ARM64 archdata access
    iommu/ipmmu-vmsa: Drop LPAE Kconfig dependency
    iommu/ipmmu-vmsa: Introduce features, break out alias
    iommu/ipmmu-vmsa: Add optional root device feature
    iommu/ipmmu-vmsa: Enable multi context support
    iommu/ipmmu-vmsa: Reuse iommu groups
    iommu/ipmmu-vmsa: Make use of IOMMU_OF_DECLARE()
    iommu/ipmmu-vmsa: Teach xlate() to skip disabled iommus
    iommu/ipmmu-vmsa: IPMMU device is 64-bit bus master
    iommu/ipmmu-vmsa: Write IMCTR twice
    iommu/ipmmu-vmsa: Make IMBUSCTR setup optional
    iommu/ipmmu-vmsa: Allow two bit SL0
    iommu/ipmmu-vmsa: Hook up r8a7795 DT matching code
    iommu/ipmmu-vmsa: Add r8a7796 DT binding
    iommu/ipmmu-vmsa: Increase maximum micro-TLBS to 48
    iommu/ipmmu-vmsa: Hook up r8a7796 DT matching code
    arm64: dts: r8a7795: Add IPMMU device nodes
    arm64: dts: r8a7795: Hook up SYS-DMAC to IPMMU
    arm64: dts: r8a7795: Point FCP devices to IPMMU
    arm64: dts: r8a7795: Connect Ethernet AVB to IPMMU
    arm64: dts: r8a7796: Add IPMMU device nodes
    clk: renesas: r8a7796: Add FCP clocks
    clk: renesas: r8a7796: Add VSP clocks
    clk: renesas: r8a7796: Add DU and LVDS clocks
    drm: rcar-du: Add R8A7796 device support
    arm64: dts: renesas: r8a7795: Remove FCP SoC-specific compatible strings
    arm64: dts: renesas: r8a7796: Add FCPF and FCPV instances
    arm64: dts: renesas: r8a7796: Add VSP instances
    arm64: dts: renesas: r8a7796: Add DU device to DT
    arm64: dts: renesas: r8a7796-salvator-x: Enable DU
), I can enable IPMMU on both the H3 and M3-W Salvator-X boards with no ill
effects on the results of the vsp-tests suite.
