So i am little skeptical about the acpi changes that i have posted. I was checking for a function equivalent in acpi as of_match_node in DT, to figure out if the iommu_spec.np that the master device is pointing to is there in the iommu_of_table and based on that we can decide if to defer the probe. I was seeing iort_scan_node was its equivalent. But if that is not correct, then last patch has to be reworked. Anyways will be good to know your feedback on this.
