[PATCH] arm64: dts: qcom: sc7180: Support ETMv4 power management

From: Sai Prakash Ranjan
Date: Fri Apr 24 2020 - 07:17:03 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.
