Subject: [PATCH 1/2] ASoC: dt-bindings: tegra: Document iommus and interconnects for ADMAIF
Date: Thu, 18 Jan 2024 15:27:05 +0100	[thread overview]
Message-ID: <20240118142706.4179146-1-thierry.reding@gmail.com> (raw)

From: Thierry Reding <treding@nvidia.com>

The ADMAIF is responsible for accessing system memory on behalf of other
components of the APE, so make sure it can be hooked up to an IOMMU and
memory controller.
