The whole point with constraints is that they describe what is safe on a given board. This includes powering off unused regulators - it should be something that the system integrator configures, not something that they get as default.
OK. So how should one describe a regulator as unused? Just leave it out since it's not wired to anything? Or have an empty node at the board level? One of the regulators involved on my board is by (hardware) default on.
Like I say do it at the board level, you know it's not connected on that board but another board may use it. -------------- next part -------------- A non-text attachment was scrubbed...
