Hi Mark and Liam, I wonder why the voltage and current regulator framework doesn't support negative voltages. We like to use the framework to specify bipolar reference voltages used with converters. However in various places negative voltages are treated as error codes, thus causing the regulator to exit on probe. As a workaround someone could say we specify positive and negative supply by label with absolute values and add the negative sign in the consumer driver. However that doesn't work well, since the bipolar 'negative' supply may also occasionally be positive. Thoughts?
