[PATCH 09/14] staging: media: tegra-vde: Add IOMMU support

2018-08-13 Thread Thierry Reding
From: Thierry Reding Implement support for using an IOMMU to map physically discontiguous buffers into contiguous I/O virtual mappings that the VDE can use. This allows importing arbitrary DMA-BUFs for use by the VDE. While at it, make sure that the device is detached from any DMA/IOMMU mapping
