Indeed, after a quick look there are tons of functions that are just stubs
;-) One thing I wonder though is why you directly use the iommu api and
not wrap it up into dma_map? Is arm infrastructure just not there yet or
do you plan to tightly integrate the tegra drm with the iommu (e.g. for
process space switching or similarly funky stuff)?
