Subject[PATCH v3 1/6] dt-bindings: iommu: mediatek: Add mediatek,infracfg phandle
Date
Add property "mediatek,infracfg" to let the mtk_iommu driver retrieve
a phandle to the infracfg syscon instead of performing a per-soc
compatible lookup in the entire devicetree and set it as a required
property for MT2712 and MT8173.
