Support this. Selective enabling of micro TLBs based on runtime device usage isn't possible at the moment due to lack of support in the IOMMU and DMA mapping APIs. Support for devices connected to different IOMMUs is also unsupported for the same reason. Signed-off-by: Laurent Pinchart --- Reading git-diff-tree failed
