The regulators are only named in the driver code, the actual control stuff is in the board file for each architecture or use case. The PN544 chip has three regulators that can be controlled or not - depending on the architecture where the chip is being used. So some of the regulators may not be controllable. In our current case the third regulator, which was missing from the code, went unnoticed because we didn't need to control it.
