Subject: [PATCH v2 07/10] arm64: tegra: Use correct compatible string for Tegra186 SMMU
Date: Tue, 20 Apr 2021 19:26:16 +0200
Message-ID: <20210420172619.3782831-8-thierry.reding@gmail.com> (raw)
In-Reply-To: <20210420172619.3782831-1-thierry.reding@gmail.com>

From: Thierry Reding <treding@nvidia.com>

The SMMU found on Tegra186 requires interoperation with the memory
controller in order to program stream ID overrides. The generic ARM SMMU
500 compatible is therefore inaccurate. Replace it with a more correct,
SoC-specific compatible string.
