[PATCH 1/4] arm64: dts: qcom: msm8998: Properly describe MMSS SMMU

From: Konrad Dybcio
Date: Wed May 31 2023 - 05:01:43 EST


The MMSS SMMU has been abusingly consuming the exposed RPM interconnect
clock and not describing the power domain it needs. Put an end to that.

Fixes: 05ce21b54423 ("arm64: dts: qcom: msm8998: Configure the multimedia subsystem iommu")
