Agreed. History here is that we have put lots of IIO supported devices in trivial-devices in the past and then it's turned out someone has them on a board where they are controllable supplies. So we end up having introduced insufficient binding docs + need to move it later. Much better to just have them documented from the start + just turn them on at driver probe and off at remove (relying on regulator subsystem support for fake supplies / fixed regulators where these operations do nothing). If someone wants to later do better power control then that can be added without adding to the binding.
