IOMMU path in sysfs was amd_iommu. After implementing multiple devices support, the path is replaced with amd_iommu_<index>. Current Thunk spec is not clear about how to support multiple instances in one block. There is no products having multiple IOMMUs yet at this point. This patch changes the path to support both amd_iommu and amd_iommu_0 for Carizo. Change-Id: I3beea2fc78d96296232226191501a02ccf20d6b1 Signed-off-by: Amber Lin <Amber.Lin@amd.com>
