From ff21776d12ff7993a6b236b8273ef62777d25dfb Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Fri, 26 Aug 2011 16:48:26 +0200 Subject: Driver core: Add iommu_ops to bus_type This is the starting point to make the iommu_ops used for the iommu-api a per-bus-type structure. It is required to easily implement bus-specific setup in the iommu-layer. The first user will be the iommu-group attribute in sysfs.
