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@xxxxxxxxxx/ 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.
