Subject: [PATCH 7/9] iommu/arm-smmu: Use Tegra implementation on Tegra186
Date: Thu, 25 Mar 2021 14:03:30 +0100 [thread overview]
Message-ID: <20210325130332.778208-8-thierry.reding@gmail.com> (raw)
In-Reply-To: <20210325130332.778208-1-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
Tegra186 requires the same SID override programming as Tegra194 in order
to seamlessly transition from the firmware framebuffer to the Linux
framebuffer, so the Tegra implementation needs to be used on Tegra186
devices as well.
