I can take a look at this part also, but CORE PM is needed for this set for testing purposes I believe, otherwise the auto-ret part does nothing and is rather impossible to test (not sure if mpu part scales without CORE PM, it might actually.) > > > - will post missing patches once possible from upstream point of view > > - voltages for vdd1 and vdd3 change when entering idle > > > > Applies on top of Kevin's for_3.2/voltage-cleanup branch. > > You can use mainline now as that branch is merged.
