This series adds DT nodes for IPMMU instances on r8a77995 together with connections to the r8a77995 on-chip device 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 A patch to enable IPMMU devices is not included in this series as Ethernet-AVB, the only device to which IPMMU is hooked up to, is disabled. The DT binding for r8a77995 has 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.
