Hi,
this patch-set makes the core code for managing iommu-groups more generic by lifting its dependencies on PCI. The core function iommu_group_get_for_dev() had a hard dev_is_pci() check in it, followed by PCI specific handling.
This check is removed in favour of the the revived device_group() iommu-ops call-back. With this call-back an IOMMU driver can define how the devices it manages are grouped together. Two functions, one generic and one for PCI devices, are provided that can be uses as a device_group() call-back or might be used in such a call-back.
The existing drivers making use of the iommu_group_get_for_dev() function are converted to this call-back.
Joerg
