From 2c1bc371268862a991a6498e1dddc8971b9076b8 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Thu, 3 Jun 2021 18:46:29 +0200 Subject: iommu/arm-smmu: Use Tegra implementation on Tegra186 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.
