+ 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.
