[PATCH 0/4] IORT SMMUv3 MSI support

[Hanjun Guo]

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().

  ACPI: IORT: lookup iort node via fwnode
  ACPI: IORT: Skip SMMUv3 device ID map for two steps mappings
