└─>Analog Devices AD7793 and similar ADCs driver
In linux kernel since version 3.1 (release Date: 2011-10-24)  
Say yes here to build support for Analog Devices AD7785, AD7792, AD7793,
AD7794 and AD7795 SPI analog to digital converters (ADC).
If unsure, say N (but it's safe to say "Y").

To compile this driver as a module, choose M here: the
module will be called AD7793.
