Note that hardware monitoring chips can include ADCs and DACs: the former to monitor system voltages, and the later to control fans (most chips use PWM for that but a few use DACs.) ADCs and DACs are, much like GPIOs, usable for a variety of different purposes. I doubt that there would be any benefit in abstracting DACs and ADCs the way we did for GPIOs, but the important point here is that we really want to group the drivers according to their functionality and not technical implementation details. -- Jean Delvare
