Subject: [PATCH 0/3] Add RPM sleep stats for MSM8916

| Series | Add RPM sleep stats for MSM8916 | expand |
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: https://lore.kernel.org/linux-arm-msm/c22d57cc-025b-5a8c-91d5-5385292da49f@codeaurora.org/ Stephan Gerhold (3): dt-bindings: soc: qcom: stats: Document qcom,rpm-legacy-stats soc: qcom: stats: Add fixed sleep stats offset for older RPM firmwares arm64: dts: qcom: msm8916: Add RPM sleep stats .../devicetree/bindings/soc/qcom/qcom-stats.yaml | 2 ++ arch/arm64/boot/dts/qcom/msm8916.dtsi | 5 +++++ drivers/soc/qcom/qcom_stats.c | 10 ++++++++++ 3 files changed, 17 insertions(+)
