The first item in the list acts as a replacement for the previous exynos_iommu_owner structure. The iommu_device member of the first list item is reported to the IOMMU core code for the master device. Signed-off-by: Joerg Roedel <jroedel at suse.de> --- drivers/iommu/exynos-io...

Okay, the structure itself is not a problem, I just thought it is not really necessary. But to keep things simple I've taken another approac...

Hi, here is a patch-set to remove all calls of iommu_group_get_for_dev() from the IOMMU drivers and move the per-device group setup and default domain allocation into the IOMMU core code. This eliminates some ugly back and forth between IOMMU core code and the IOMMU drivers, where the driver called iommu_group_get_for_dev() which itself called back into the driver. The patch-set started as a

...other platform device (thus IOMMU > controller) is is probed. It doesn't handle EPROBE_DEFER too. I don't quite understand why probe_device() is called too early, as it is called at the same time add_device() was called before. But anyway, I have seen a similar problem on OMAP. If the SYSMMU for a master is not probed yet when probe_device() is called, it can just return -ENODEV and in your driver you just call but_iommu_probe() when a new SYSMMU got initialized to re-probe uninitialized masters on the bus. This patch-set contains a change to export bus_iommu_probe() for exactly that r...
