Hi, here is a small patch-set for the omap-iommu driver to make it use new features of the iommu-core. Please review.

From: Joerg Roedel <jroedel@suse.de>
Support for IOMMU groups will become mandatory for drivers,
so add it to the omap iommu driver.

Thanks for the patches - this has been on my TODO list but you beat me in getting there first :). Are these for 4.12? I have given the series a quick try and these currently break the functionality. I am investigating the failures, so will mostly need some additional changes. Let me know if you want me to take up posting of the v2. Meanwhile, I have added some comments on the patches. regards Suman > > Thanks, > > Joerg > > Joerg Roedel (5): > iommu/omap: Move data structures to omap-iommu.h > iommu/omap: Permanently keep iommu_dev pointer in arch_data > iommu/omap: Set dev->archdata.iommu = NULL in omap_iommu_remove_device > iommu/omap: Make use of 'struct iommu_device' > iommu/omap: Add iommu-group support > > drivers/iommu/omap-iommu.c | 137 ++++++++++++++++++++----------- > drivers/iommu/omap-iommu.h | 35 ++++++++ > include/linux/platform_data/iommu-omap.h | 15 ---- > 3 files changed, 124 insertions(+), 63 deletions(-) >
