[PATCH v2 1/7] dt-bindings: iommu: mediatek: Add phandles for mediatek infra/pericfg

AngeloGioacchino Del Regno
2022-05-18T10:05:21Z

Add properties "mediatek,infracfg" and "mediatek,pericfg" to let the
mtk_iommu driver retrieve phandles to the infracfg and pericfg syscon(s)
instead of performing a per-soc compatible lookup.
