From: Hanjun Guo <redacted> IORT revision C introduced SMMUv3 MSI support for control interrupts, which introduced a device ID mapping index to retrieve the dev ID and ITS parent, adding its support in this patch set, please refer to each patch for detail commit message. RFC v1 -> RFC v2: - Introduce a new API iort_set_device_domain() to find the MSI domain for an SMMUv3 (or any other IORT table node) to reduce the complex of doing that via acpi_configure_pmsi_domain().
