Subject: [PATCH v3 7/9] arm64: tegra: Use correct compatible string for Tegra186 SMMU
Date: Thu, 3 Jun 2021 18:46:30 +0200 [thread overview]
Message-ID: <20210603164632.1000458-8-thierry.reding@gmail.com> (raw)
In-Reply-To: <20210603164632.1000458-1-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.
