Subject: [PATCH v2] iommu/arm-smmu-qcom: Add SM8450 MDSS compatible
Date: Sat, 11 Jul 2026 23:14:01 -0400 [thread overview]
Message-ID: <20260711-sm8450-qol-smmu-v2-1-41a6fba41c3e@proton.me> (raw)
From: Esteban Urrutia <esteuwu@proton.me>
Add the compatible for the MDSS client on the Snapdragon 8 Gen 1 so it can
be properly configured by the IOMMU driver.
Otherwise, there is an unhandled context fault, because the framebuffer is
already configured in UEFI.
Reviewed-by: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>
Signed-off-by: Esteban Urrutia <esteuwu@proton.me>

This patch allows the MDSS driver to properly function on SM8450 based
devices.

Changes in v2:
- Split series in subseries (dispcc, dts, qmp, smmu)
