Subject: [PATCH v3] media: dt: bindings: tegra-vde: Document new optional IOMMU property
Date: Sun, 23 Jun 2019 20:07:26 +0300 [thread overview]
Message-ID: <20190623170730.5095-4-digetx@gmail.com> (raw)
In-Reply-To: <20190623170730.5095-1-digetx@gmail.com>
All NVIDIA Tegra SoC generations provide IOMMU support for the video
decoder engine. Document new optional device-tree property that connects
VDE with the IOMMU provider.
