Subject: [PATCH 1/2] arm64: dts: qcom: sc7180: Support ETMv4 power management
Date: Fri, 15 May 2020 16:21:36 +0530	[thread overview]
Message-ID: <b0a2ac4ffefe7d3e216a83ab56867620f120ff08.1589539293.git.saiprakash.ranjan@codeaurora.org> (raw)
In-Reply-To: <cover.1589539293.git.saiprakash.ranjan@codeaurora.org>

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.
