| The Exynos System MMU driver unconditionally executes code and registers | ||||
| a struct iommu_ops with the platform bus irrespective of whether it runs | ||||
| on an Exynos SoC or not. This causes problems in multi-platform kernels | ||||
| where drivers for other SoCs will no longer be able to register their | ||||
| own struct iommu_ops or even try to use a struct iommu_ops for an IOMMU | ||||
| that obviously isn't there. | ||||
| 
 | ||||
| The smallest fix I could think of is to check for the existence of any | ||||
| Exynos System MMU devices in the device tree and skip initialization | ||||
| otherwise. | ||||
| 
 | ||||
| This fixes a problem on Tegra20 where the DRM driver will try to use the | ||||
| obviously non-existent Exynos System MMU. | ||||
