Configure MFD device drivers.
|
||||
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.
