In the patch ("drivers: base: Add bits to struct device to control
iommu strictness") we add the ability for devices to tell us about
their IOMMU strictness requirements. Let's now take that into account
in the IOMMU layer.
A few notes here:

In the patch ("drivers: base: Add bits to struct device to control
iommu strictness") we add the ability for devices to tell us about
their IOMMU strictness requirements. Let's now take that into account
in the IOMMU layer.
A few notes here:
