That could be in the probe_device() call-back, no?

device_probe() is exynos_sysmmu_probe(), then yes, this is called before any of the xlate() calls are made.
Would it work to keep the iommu_device structures in the sysmmus and also create them for the owners? This isn't really a nice solution but should work the the IOMMU driver until there is a better way to fix this.

Joerg
