H A Dmux-controller.txt4 A multiplexer (or mux) controller will have one, or several, consumer devices
5 that uses the mux controller. Thus, a mux controller can possibly control
7 multiplexer needed by each consumer, but a single mux controller can of course
10 A mux controller provides a number of states to its consumers, and the state
11 space is a simple zero-based enumeration. I.e. 0-1 for a 2-way multiplexer,
12 0-7 for an 8-way multiplexer, etc.
