Re: [PATCH v3 4/6] arm64: dts: mediatek: mt2712e: Add mediatek,infracfg phandle for IOMMU

From: Miles Chen
Date: Thu Jun 09 2022 - 14:09:09 EST


> The IOMMU driver now looks for the "mediatek,infracfg" phandle as a
> new way to retrieve a syscon to that:
> even though the old way is retained, it has been deprecated and the
> driver will write a message in kmsg advertising to use the phandle
> way instead.

> For this reason, assign the right phandle to mediatek,infracfg in
> the iommu node.
