From 11a8c5e3a94b12848f24d9c63b5c175ce0b80729 Mon Sep 17 00:00:00 2001 From: Jean-Philippe Brucker Date: Fri, 18 Jun 2021 17:20:57 +0200 Subject: ACPI: Move IOMMU setup code out of IORT Extract the code that sets up the IOMMU infrastructure from IORT, since it can be reused by VIOT. Move it one level up into a new acpi_iommu_configure_id() function, which calls the IORT parsing function which in turn calls the acpi_iommu_fwspec_init() helper.
