The patch is implementing the get and set voltage operations, the regulators were actually supported. The errors were being caused by the DT attempting to set the voltage for a fixed voltage regulator which obviously won't work - I suspect that the DTs might not be ideal, it seems common to overspecify voltages in DTs for some reason.
