[PATCH 0/4] tegra: DMA mask and IOMMU bit fixes
These 4 patches fix two issues that existed on Tegra regarding DMA:
1) The bit indicating whether to use an IOMMU or not was hardcoded ; make this
a platform property and use it in instmem
2) The DMA mask was not set for platform devices. Fix this by converting
more pci_dma* to the DMA API, and use that more generic code to set the
DMA mask properly for all platforms.
Tested on both x86

[PATCH v5 0/7] Add virtio-iommu driver
Implement the virtio-iommu driver, following specification v0.9 [1].
Since v4 [2] I fixed the issues reported by Eric, and added Reviewed-by
from Eric and Rob. Thanks!
I changed the specification to fix one inconsistency discussed in v4.
That the device fills the probe buffer with zeroes is now a "SHOULD"
instead of a "MAY", since it's the only way for the driver to know
