All PMBus devices are by definition regulators with input and output voltages.
After all, PMBus stands for "Power Management Bus". Some of them are listed
in trivial devices, some are not. Is that a general guidance, or in other
words should I (we) automatically reject patches adding PMBus devices
to the trivial devices file ?
