There is a log message "no parameters" for each regulator. This is printed unconditionally from print_constraints(). Looking through the code again, looks like this is on purpose. It is just a bit annoying to get lots of those messages. One of the systems I am dealing with has 17 LTC2978 chips in it, with 8 channels each. That results in 136 times "no parameters" in the boot log. And that is not even a fully populated system; if fully populated, there can be more than 60 of those chips. 500+ lines of similar log messages is really a bit on the high side. It might help if there was a way to silence the messages, ie to make "print_constraints" optional. Thanks, Guenter
