+Multiplexer/DeMultiplexer Switches
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+USB Type-C connectors may have one or more mux/demux switches behind them. Since
+the plugs can be inserted right-side-up or upside-down, a switch is needed to
+route the correct data pairs from the connector to the USB controllers. If
+Alternate or Accessory Modes are supported, an other switch is needed that can
+route the pins on the connector to some other component besides USB. USB Type-C
+Connector Class supplies an API for registering those switches.
+
+.. kernel-doc:: drivers/usb/typec/mux.c
+   :functions: typec_switch_register typec_switch_unregister typec_mux_register typec_mux_unregister
+
+In most cases the same physical mux will handle both the orientation and mode.
+However, as the port drivers will be responsible of the orientation, and the
+alternate mode drivers of the mode, the two are always separated into their own
+logical components: "mux" for the mode and "switch" for the orientation.
+
+When a port is registered, USB Type-C Connector Class requests both the mux and
+the switch for the port. The drivers can then use the following API for
+controlling them:
+
+.. kernel-doc:: drivers/usb/typec/class.c
+   :functions: typec_set_orientation typec_set_mode
+
+If the connector is dual-role capable, there may also be a switch for the data
+role. USB Type-C Connector Class does not supply separate API for them. The
+port drivers can use USB Role Class API with those.
+
+Illustration of the muxes behind a connector that supports an alternate mode:
