In mt8195, we have a new IOMMU that is for INFRA IOMMU. its masters mainly are PCIe and USB. Different with MM IOMMU, all these masters connect with IOMMU directly, there is no mediatek,larbs property for infra IOMMU. Another thing is about PCIe ports. currently the function "of_iommu_configure_dev_id" only support the id number is 1, But our PCIe have two ports, one is for reading and the other is for writing. see more about the PCIe patch in this patchset. Thus, I only list the reading id here and add the other id in our driver.
