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.
Ah, from the constraints rather than from the DT parsing. I do like having it there since it's enormously helpful in debugging and that is a... specialist number of regulators you have in your system. We can definitely at least add a boot argument or something to suppress them, let me have a think if we want to do that by default.
