[PATCH v6 00/11] soc: qcom: spm: add support for SPM regulator

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

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.
