+          Multifunction devices embed several functions (e.g. GPIOs,
+          touchscreens, keyboards, current regulators, power management chips,
+          etc...) in one single integrated circuit. They usually talk to the
+          main CPU through one or more IRQ lines and low speed data busses (SPI,
+          I2C, etc..). They appear as one single device to the main system
+          through the data bus and the MFD framework allows for sub devices
+          (a.k.a. functions) to appear as discrete platform devices.
+          MFDs are typically found on embedded platforms.
+
+          This option alone does not add any kernel code.
