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.
