From 33b21a6b203f70e2012b02753134e59c3ab38779 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Tue, 5 Jul 2016 13:07:53 +0200 Subject: iommu: Add apply_dm_region call-back to iommu-ops This new call-back will be used by the iommu driver to do reserve the given dm_region in its iova space before the mapping is created. The call-back is temporary until the dma-ops implementation is part of the common iommu code.
