    Subject[PATCH v3 13/14] staging: typec: fusb302: Hook up mux support using tcpc_gen_mux support
    Date
    Add mux support to the fusb302 driver, call devm_tcpc_gen_mux_create()
    to let the generic tcpc_mux_dev code create a tcpc_mux_dev for us.

    Also document the mux-names used by the generic tcpc_mux_dev code in
    our devicetree bindings.

    Changes in v3:
    -Drop devicetree bindings documentation, since this is only used with
    device-properties set by platform code on X86/ACPI now, we don't need
    bindings yet
