    mux: minimal mux subsystem · a3b02a9c
    Peter Rosin authored
    Add a new minimalistic subsystem that handles multiplexer controllers.
    When multiplexers are used in various places in the kernel, and the
    same multiplexer controller can be used for several independent things,
    there should be one place to implement support for said multiplexer
    A single multiplexer controller can also be used to control several
    parallel multiplexers, that are in turn used by different subsystems
    in the kernel, leading to a need to coordinate multiplexer accesses.
    The multiplexer subsystem handles this coordination.
    Thanks go out to Lars-Peter Clausen, Jonathan Cameron, Rob Herring,

    Kroah-Hartman and last but certainly not least to Philipp Zabel for
    helpful comments, reviews, patches and general encouragement!
