I think it is better let Mediatek SoC maintainer Matthias to accept dtsi
patch like other drivers. This can avoid dtsi conflict. As I
remember,last time MT8173 IOMMU dtsi patch accepted in iommu tree and
mt8173.dtsi had conflict with arm soc tree at the merge window. Honghui
should resend this patch to Matthias, and elaborate your dependency with
clock and power domain dtsi, then Matthias know the merge sequence.
