Subject: [PATCH 16/18] staging/media/tegra-vde: Clean up IOMMU workaround
Date: Thu, 20 Aug 2020 16:08:35 +0100 [thread overview]
Message-ID: <3535c205b9bce52556abbf2f63384fb38e009df9.1597931876.git.robin.murphy@arm.com> (raw)
In-Reply-To: <cover.1597931875.git.robin.murphy@arm.com>
Now that arch/arm is wired up for default domains and iommu-dma, we no
longer need to work around the arch-private mapping.
