Subject: Aw: Re: [PATCH] arm64: dts: mt7622: fix switch probe on
bananapi-r64
Hi,
i can confirm that daniels patch pointed by arinc fixes driver for the wrong devicetree on BPI-R64.
but there are concerns from the netdev/dsa maintainers in its current state
https://patchwork.kernel.org/project/linux-mediatek/patch/11f5f127d0350e72569c36f9060b6e642dfaddbb.1714514208.git.daniel@makrotopia.org/
regards Frank
