  10           Multifunction devices embed several functions (e.g. GPIOs,
  11           touchscreens, keyboards, current regulators, power management chips,
  12           etc...) in one single integrated circuit. They usually talk to the
  13           main CPU through one or more IRQ lines and low speed data busses (SPI,
  14           I2C, etc..). They appear as one single device to the main system
  15           through the data bus and the MFD framework allows for sub devices
  16           (a.k.a. functions) to appear as discrete platform devices.
  17           MFDs are typically found on embedded platforms.
