But it's not allowed to change voltage of a dummy regulator, is it
intentional?

Of course not, we can't know if the requested new voltage is valid - the
driver would have to have explict support for handling situations where
it's not possible to change the voltage (which it can detect through
enumerating the values it wants to set at startup).

[Requesting the same supply multiple times]

But how driver is supposed to recognize that it's a dummy or buggy
regulator if it rejects all voltages?
