# # Multifunction miscellaneous devices # menuconfig MFD_SUPPORT bool "Multifunction device drivers" depends on HAS_IOMEM default y help Multifunction devices embed several functions (e.g. GPIOs, touchscreens, keyboards, current regulators, power management chips, etc...) in one single integrated circuit.
