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 v2 -> v1: - Drop RFC tag; - return the index value directly from iort_get_id_mapping_index() then make the logic simple in iort_node_map_id(); - To make sure ID mapping index is only ignored if all interrupts are GSIV based - Sqursh part of the patch 4 to patch 3 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().
