I think iommu_device_set_fwnode() is not enough for of_iommu_xlate()
to find the IOMMU. The IOMMU is actually added to the IOMMU list by
iommu_device_register(), which is last in the sequence, so I guess we
should be fine.
hmmm, the later patch would change that ;) i'll fix it in the next version.
Best regards,
Tomasz
