Subject: [PATCH 0/3] Add RPM sleep stats for MSM8916
Date: Mon, 18 Oct 2021 13:08:00 +0200 [thread overview]
Message-ID: <20211018110803.32777-1-stephan@gerhold.net> (raw)
MSM8916 is similar to the other SoCs that had the RPM stats node added
in commit 290bc68 ("arm64: dts: qcom: Enable RPM Sleep stats").
However, the dynamic offset readable at 0x14 seems only available on
some of the newer RPM firmware versions.
To be absolutely sure, this series adds a new qcom,rpm-legacy-stats
compatible that reads the sleep stats from a fixed offset of 0xdba0.
This approach was originally suggested by Maulik Shah in:
