Subject: [PATCH] iommu/arm-smmu: wire up map_sg for arm-smmu-v3
Date: Fri, 3 Jun 2016 11:50:30 +0100 [thread overview]
Message-ID: <1464951030-14044-1-git-send-email-will.deacon@arm.com> (raw)
From: Jean-Philippe Brucker <jean-philippe.brucker@arm.com>
The map_sg callback is missing from arm_smmu_ops, but is required by
iommu.h. Similarly to most other IOMMU drivers, connect it to
default_iommu_map_sg.
