Subject[PATCH 2/3] dts: arm64/sdm845: Add node for qcom,smmu-v2
Date
Add device node for qcom,smmu-v2 available on sdm845.
This smmu is available only to GPU device.

Signed-off-by: Vivek Gautam <vivek.gautam@codeaurora.org>

One power domain required for this GPU smmu - GPU_CX_GDSC,
commented out in the node is coming from gpu clock controller [1].
