From 5fba66d42746c9b8063de7ce4565d0173da657a2 Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Thu, 12 Jan 2023 20:11:04 -0800 Subject: [PATCH] iommu/arm-smmu-qcom: Select identity domain for sc8280xp MDSS The Qualcomm display driver installs a translation domain once it has mapped a framebuffer. Use the identity domain for this device on SC8280XP as well, to avoid faults from EFI FB accessing the framebuffer while this is being set up.
