Shared kernel infrastructure that implements common IOMMU page-table formats, used by actual IOMMU drivers (such as those for AMD, Intel, and ARM SMMU hardware) rather than talking to any hardware itself. It is a code library that lives alongside the IOMMU subsystem to avoid duplicating page-table walking and management logic across vendor drivers.
This is not actually a driver directory; it is a support library inside the IOMMU subsystem that provides common page-table format code consumed by the real IOMMU drivers. It has no hardware of its own to deprecate or keep, so the driver-lifecycle question does not apply.

codex reasoning notes (technical)
Not a driver directory: generic IOMMU page-table format/library code shared by other drivers, not a hardware-bound kernel driver.
