Current IORT code provides a function (ie iort_get_fwnode()) which looks up a struct fwnode_handle pointer through a struct acpi_iort_node pointer for SMMU components but it lacks a function that implements the reverse look-up, namely struct fwnode_handle* -> struct acpi_iort_node*. Devices that are not IORT named components cannot be retrieved through their associated IORT named component scan interface because they just are not represented in the ACPI namespace; the reverse look-up is therefore required for all platform devices that represent IORT nodes (eg SMMUs) so that the struct acpi_iort_node* can be retrieved from the struct device->fwnode pointer.
