Subject: [PATCH v2 0/3] iommu/vt-d: Add support for ACPI/SATC table

The Intel VT-d specification v3.2 comes with a new ACPI SATC (SoC-
Integrated Address Translation Cache) reporting structure. The SoC
integrated device enumerated in this table has a functional
requirement to enable its ATC (Address Translation Cache) via the
ATS capability for device operation.

This patch set adds the code to parse the SATC table, enumerates the
devices in it and satisfies the ATS requirement for them. Please help
to review. I will queue it in VT-d update for v5.12 if no objection.

  iommu/vt-d: Parse SATC reporting structure
  iommu/vt-d: Apply SATC policy
