[PATCH 1/2] arm64: dts: qcom: sc7180: Support ETMv4 power management
From: Sai Prakash Ranjan
Date: Fri May 15 2020 - 06:52:12 EST
Now that deep idle states are properly supported on SC7180,
we need to add "coresight-loses-context-with-cpu" property
to avoid failure of trace session because of losing context
on entering deep idle states.

Resending this because the last patch sent here - https://lore.kernel.org/patchwork/patch/1230367/
seems to have added "coresight-loses-context-with-cpu" to
replicator node instead of etm7 node.
