Hi All, Please find the below patch and let me know your suggestions on this.
With this patch iommu groups can be linked and iommu driver will get to know which all iommu groups belongs to a particular iommu device. Each iommu device might have multiple iommu groups, with each group populated with many devices. With this configuration, iommu driver may require a list of iommu groups belonging to each iommu device. Add list_head struct entry in iommu_group.
