From dfdbf16c50d89a8cb102a5f7a1f53686fff506ad Mon Sep 17 00:00:00 2001 From: Jonathan Hunter Date: Thu, 2 May 2019 14:27:21 +0100 Subject: [PATCH] arm64: tegra: Fix insecure SMMU users for Tegra186 Commit 954a03be033c ("iommu/arm-smmu: Break insecure users by disabling bypass by default") intentionally breaks all devices using the SMMU in bypass mode. This is breaking various devices on Tegra186 which include the ethernet, BPMP and HDA device. Fix this by populating the iommus property for these devices with their stream ID.
