Hi All,
Patch 1/2 was posted as part of series [1] as pointed out by Geert we need to
have an entry in both the lists soc_rcar_gen3 and soc_rcar_gen3_whitelist to
enable iommu unconditionally, this is now fixed in patch 1/2, also note the DT
binding documentation for R8A774E1 is part of [1]. Where as patch 2/2 is a
similar FIX for r8a77961.
Cheers,
Prabhakar

Add an entry for r8a77961 in soc_rcar_gen3[] list so that we dont
enable iommu unconditionally.
