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.
