If we have that file, we will know there is only 3 larbs in mt8167. thus, here should be: larbid_remap = {0, 1, 2} Other than this, Reviewed-by: Yong Wu <yong.wu@mediatek.com> > +}; > + > static const struct mtk_iommu_plat_data mt8173_data = { > .m4u_plat = M4U_MT8173, > .has_4gb_mode = true, > @@ -799,6 +807,7 @@ static const struct mtk_iommu_plat_data mt8183_data = { > > static const struct of_device_id mtk_iommu_of_ids[] = { > { .compatible = "mediatek,mt2712-m4u", .data = &mt2712_data}, > + { .compatible = "mediatek,mt8167-m4u", .data = &mt8167_data}, > { .compatible = "mediatek,mt8173-m4u", .data = &mt8173_data}, > { .compatible = "mediatek,mt8183-m4u", .data = &mt8183_data}, > {} > diff --git a/drivers/iommu/mtk_iommu.h b/drivers/iommu/mtk_iommu.h > index 4696ba027a71..72f874ec9e9c 100644 > --- a/drivers/iommu/mtk_iommu.h > +++ b/drivers/iommu/mtk_iommu.h > @@ -30,6 +30,7 @@ struct mtk_iommu_suspend_reg { > enum mtk_iommu_plat { > M4U_MT2701, > M4U_MT2712, > + M4U_MT8167, > M4U_MT8173, > M4U_MT8183, > };
