Currently configurations can be generated where IOMMU_SUPPORT is disabled but IOMMU_IOVA is built as a module and DRM_TEGRA as built-in. In such a case, the symbols guarded by IOMMU_IOVA will not be available when linking the Tegra DRM driver and cause a linking failure. Simplify this by unconditionally selecting IOMMU_IOVA, which makes sure that it will be forced to =y if DRM_TEGRA=y. Technically we can now get IOMMU_IOVA code built-in even if we don't use it (Tegra DRM only uses it when IOMMU_SUPPORT is also enabled), but such configuration are of a mostly academic nature. In all practical configurations we want IOMMU support anyway. Signed-off-by: Thierry Reding <treding@nvidia.com>

Choose this option if you have an NVIDIA Tegra SoC.

To compile this driver as a module, choose M here: the module

will be called tegra-drm.

Say yes if HOST1X should be available for userspace DRM users.
