This series adds DT nodes for IPMMU instances on r8a77970 together with connections to r8a77970 on-chip devices: SYS-DMAC and Ethernet-AVB. With these patches applied a white list enabled IPMMU driver may be used to check silicon revision and then enable IPMMU in the known working cases. The recommended IPMMU driver patch is iommu/next with the following applied: [PATCH v5 00/09] iommu/ipmmu-vmsa: r8a7795 support V5 [PATCH v4 0/3] iommu/ipmmu-vmsa: r8a7796 support V4 [PATCH 0/2] iommu/ipmmu-vmsa: r8a779(70|95) support The final patch in the series enable IPMMU support for all IPMMU instances on r8a77970 that are used by IPMMU devices listed above. The DT binding for r8a77970 are been submitted (as part of the r8a779(70|95) series noted above) in conjunction with this patchset. This is based on work by Magnus Damm.
