2 # Multifunction miscellaneous devices
6 bool "Multifunction device drivers"
10 Multifunction devices embed several functions (e.g. GPIOs,
11 touchscreens, keyboards, current regulators, power management chips,

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
