Hi  I am not sure if the question belongs here (probably belongs to linux-power list which I didnt find). My questions is about the usage of regulation_constraints. How do we initialize the constraints for a regulator which needs to be powered on at boot time only? I tried the "always_on" flag but that seems to be causing "regulator_disable" to bypass the call to regulator_ops->disable. I need to disable the regulator, say during power off. ÂAlso if we turn on "has_full_constraints" for the board, any regulator which is not "always_on" is disabled during initialization. On the other hand, if the "has_full_constraints" is turned off, we get warnings from the core. So I am confused about the usage of the regulator core API for the case of a regulator which needs to be "enabled" only during init.
