Subject: Re: [PATCH v3 3/6] arm64: dts: mediatek: mt8173: Add mediatek, infracfg phandle for IOMMU
Date: Fri, 10 Jun 2022 02:06:05 +0800 [thread overview]
Message-ID: <20220609180605.31142-1-miles.chen@mediatek.com> (raw)
In-Reply-To: <20220609100802.54513-4-angelogioacchino.delregno@collabora.com>
> 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.
