From: Jan Kiszka <jan.kiszka@siemens.com> The PVU allows to define a limited set of mappings for incoming DMA requests to the system memory. It is not a real IOMMU, thus hooked up under the TI SoC bindings.
You still keep developing it on wrong, old kernel (or not using get_maintainers.pl, but this one seems too obvious so I assumed wrong kernel).
