From: Hanjun Guo <hanjun.guo at linaro.org>

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().

Hanjun Guo (3):
  ACPICA: Add SMMUv3 device ID mapping index support
  ACPI: IORT: lookup iort node via fwnode
  ACPI: IORT: Skip SMMUv3 device ID map for two steps mappings

Lorenzo Pieralisi (1):
  ACPI: IORT: SMMUv3 nodes MSI support
