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 test stack for this patchset is a merge of
* The iommu/next branch of the vfio tree
* renesas-devel-20171110-v4.14-rc8 tag of the renesas tree
With the following applied:
[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.
Based on renesas-devel-20171110-v4.14-rc8
Changes since V1:
* Drop mostly redundant comments from nodes
