Subject[PATCH 3/3] iommu: Enable compile testing for some of drivers
Date
Some of the IOMMU drivers can be compile tested to increase build
coverage. The OMAP, Rockchip and Exynos drivers use
device.dev_archdata.iommu field which does not exist on all platforms.
The sPAPR TCE and ARM SMMU have also restrictions where they can be
built.
