Subject: [PATCH 2/3] ARM: dts: qcom: sdx55: Add Qcom SMMU-500 as the fallback for IOMMU node
SDX55 uses the Qcom version of the SMMU-500 IP. So use "qcom,smmu-500"
compatible as the fallback to the SoC specific compatible.
Cc: <stable@...r.kernel.org> # 5.12
Fixes: a2bdfdfba2af ("ARM: dts: qcom: sdx55: Enable ARM SMMU")
