+         If you say yes to this option, support will be included for a
+         GPIO based I2C multiplexer. This driver provides access to
+         I2C busses connected through a MUX, which is controlled
+         through GPIO pins.
+
+         This driver can also be built as a module.  If so, the module
+         will be called gpio-i2cmux.
