Subject: [PATCH v2 2/2] arm64: tegra: Enable audio IOMMU support on Tegra194
Date: Thu,  8 Jul 2021 12:34:32 +0200	[thread overview]
Message-ID: <20210708103432.1690385-3-thierry.reding@gmail.com> (raw)
In-Reply-To: <20210708103432.1690385-1-thierry.reding@gmail.com>

From: Thierry Reding <treding@nvidia.com>

Add iommus and interconnects properties to the ADMAIF device tree node
on Tegra194. This ensures that the correct SID is used for translation
of physical to I/O virtual addresses and that the path to system memory
is properly described, which in turn can impact the range of memory that
the device can address.
