This series adds DT nodes for IPMMU instances on r8a7796 together with
connections to various r8a7796 on-chip devices such as Audio-DMAC, SYS-DMAC,
Ethernet-AVB and a bunch of multimedia devices that make use of FCP.
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
The final patch in the series enable IPMMU support for all IPMMU
instances on r8a7796 that are used by IPMMU devices listed above.
The DT binding for r8a7796 have been acked (as part of the r8a7796 series
noted above) but have not yet been merged.
Based on work by Magnus Damm.
