[PATCH 0/6] Support CPR on MSM8916

[Stephen Boyd]

This patch series adds support for CPR on MSM8916. It depends on
a few different patch series to be fully functional. It needs SPMI
regulator support[1] and secondly it needs the NVMEM framework[2].
It also needs a patch that provides a "corner" voting mechanism to the
SMD RPM regulators (and it relies on the SMD RPM regulators to function
properly). If possible I would like to get rid of that patch entirely.
Finally it needs CPU clock support to support scaling CPU frequencies.
Once you have those 4 or 5 patch series in place you can apply these
patches and enable cpufreq-dt and add the cpufreq-dt device (maybe the
CPR driver should add the cpufreq-dt device?) and you'll see interrupts
for CPR and OPP voltage adjustments triggering CPUfreq to modify voltages.

Stephen Boyd (6):
  regulator: core: Don't spew backtraces on duplicate sysfs
  regulator: core: Print at debug level on debugfs creation failure
  PM / OPP: Support adjusting OPP voltages at runtime
  OPP: Allow notifiers to call dev_pm_opp_get_{voltage,freq} RCU-free
  cpufreq-dt: Handle OPP voltage adjust events
  power: avs: Add support for CPR (Core Power Reduction)
