The DT change used in the downstream kernel is from here:
https://patchwork.kernel.org/project/linux-mediatek/patch/1616499241-4906-9-git-send-email-andrew-sh.cheng@mediatek.com/
Might need some update (eg. add the cci property in cpu) though.
Rex, you can also include the 8183 DT change in the next version since
most of the mt8183 dts are in the mainline.
