Subject: [PATCH 10/12] ARM: tegra: Enable IOMMU for display controllers on Tegra30
Date: Mon, 13 Oct 2014 12:33:52 +0200 [thread overview]
Message-ID: <1413196434-5292-10-git-send-email-thierry.reding@gmail.com> (raw)
In-Reply-To: <1413196434-5292-1-git-send-email-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
Add iommus properties to the device tree nodes for the two display
controllers found on Tegra30. This will allow the display controllers to
map physically non-contiguous buffers to I/O virtual contiguous address
spaces so that they can be used for scan-out.
