The apq8064 rework to use cacheinfo takes more than expected, so I've spanwed this series. It is an excerpt of the APQ8064 cpufreq series [1], so it it continues the version numbering for those patches. The Subsystem Power Manager (SPM) / SPM AutoVoltageScaling Wrapper2 (SAW2) are hardware blocks used on some of Qualcomm platforms to handle the voltage rails. It does this by bypassing RPM and directly interfacing the PMIC. Extend current SPM driver to export this regulator. [1] https://lore.kernel.org/linux-arm-msm/20230827115033.935089-1-dmitry.baryshkov@linaro.org/ Changes since v6: - Added SoC-specific compat strings on MSM8960, IPQ4019, IPQ8064 platforms (Luca) - Fixed saw2 node names on few remaining platforms. Changes since v5: - Added patch that moves SPM structs out of the header file - Removed support for L2 SAW regulator (Stephan Gerhold). msm8960/apq8064 do not use this SAW2 to manage this regulator and other platforms will need changes anyway. --- Dmitry Baryshkov (22): dt-bindings: soc: qcom: merge qcom,saw2.txt into qcom,spm.yaml dt-bindings: soc: qcom: qcom,saw2: add missing compatible strings dt-bindings: soc: qcom: qcom,saw2: define optional regulator node soc: qcom: spm: remove driver-internal structures from the driver API soc: qcom: spm: add support for voltage regulator ARM: dts: qcom: apq8084: use new compat string for L2 SAW2 unit ARM: dts: qcom: msm8974: use new compat string for L2 SAW2 unit ARM: dts: qcom: msm8960: use SoC-specific compatibles for SAW2 devices ARM: dts: qcom: ipq4019: use SoC-specific compatibles for SAW2 devices ARM: dts: qcom: ipq8064: use SoC-specific compatibles for SAW2 devices ARM: dts: qcom: apq8064: rename SAW nodes to power-manager ARM: dts: qcom: apq8084: rename SAW nodes to power-manager ARM: dts: qcom: msm8960: rename SAW nodes to power-manager ARM: dts: qcom: msm8974: rename SAW nodes to power-manager ARM: dts: qcom: ipq4019: rename SAW nodes to power-manager ARM: dts: qcom: ipq8064: rename SAW nodes to power-manager ARM: dts: qcom: apq8064: declare SAW2 regulators ARM: dts: qcom: msm8960: declare SAW2 regulators ARM: dts: qcom: apq8084: drop 'regulator' property from SAW2 device ARM: dts: qcom: msm8974: drop 'regulator' property from SAW2 device ARM: dts: qcom: ipq4019: drop 'regulator' property from SAW2 devices ARM: dts: qcom: ipq8064: drop 'regulator' property from SAW2 devices .../devicetree/bindings/arm/msm/qcom,saw2.txt | 58 ----- .../soc/qcom/{qcom,spm.yaml => qcom,saw2.yaml} | 45 +++- arch/arm/boot/dts/qcom/qcom-apq8064.dtsi | 32 ++- arch/arm/boot/dts/qcom/qcom-apq8084.dtsi | 13 +- arch/arm/boot/dts/qcom/qcom-ipq4019.dtsi | 25 +- arch/arm/boot/dts/qcom/qcom-ipq8064.dtsi | 10 +- arch/arm/boot/dts/qcom/qcom-msm8960.dtsi | 20 +- arch/arm/boot/dts/qcom/qcom-msm8974.dtsi | 13 +- drivers/soc/qcom/spm.c | 254 ++++++++++++++++++++- include/soc/qcom/spm.h | 23 +- 10 files changed, 353 insertions(+), 140 deletions(-) --- base-commit: 39676dfe52331dba909c617f213fdb21015c8d10 change-id: 20240101-saw2-spm-regulator-af0f81c15cdc Best regards,
