# # Multiplexer devices # menuconfig MULTIPLEXER tristate "Multiplexer subsystem" help Multiplexer controller subsystem. Multiplexers are used in a variety of settings, and this subsystem abstracts their use so that the rest of the kernel sees a common interface. When multiple parallel multiplexers are controlled by one single multiplexer controller, this subsystem also coordinates the multiplexer accesses. To compile the subsystem as a module, choose M here: the module will be called mux-core.
