└─> Export IOMMU internals in DebugFS

Allows exposure of IOMMU device internals. This option enables
the use of debugfs by IOMMU drivers as required. Devices can,
at initialization time, cause the IOMMU code to create a top-level
debug/iommu directory, and then populate a subdirectory with
entries as required.
