[PATCH 2/2] iommu/ipmmu-vmsa: Hook up r8a779(70|95) DT matching code

[Simon Horman]

Support the r8a77970 (R-Car V3M) and r8a77995 (R-Car D3) IPMMUs by sharing
feature flags with r8a7795 (R-Car H3) and r8a7796 (R-Car M3-W). Also update
IOMMU_OF_DECLARE to hook up the compat strings.

This last dependent patch series hasn't had any comments or updates
since June.  Do I take it from Simon's new patches here that it's still
relevant and desired?  Perhaps it was simply missed and nobody bothered
to re-send it?  Thanks,

Alex

Hi Alex,

I spoke with Magnus about this and we feel that its a little early
to merge the driver portion of both "[PATCH v4 0/3] iommu/ipmmu-vmsa:
r8a7796 support V4" and this patchset.

We would, however, like to see the bindings updates merged as they seem
ready. I will repost them separately as that should be easiest for you.
