I would suggest defining a subnode with boolean properties for these, it's not massively legible to have this many random numbers. Consider using the regulator binding, microphone biases are after all regulators. > + The fifth cell a non-zero value indicates the micbias should be bypassed > + and simply output MICVDD This is something that should be being varied at runtime in detection scenarios, the meaning ought to be being tightened up here.
