Say yes here to build support for Analog Devices AD5024, AD5025, AD5044,
AD5045, AD5064, AD5064-1, AD5065, AD5628, AD5648, AD5668 Digital to Analog
Converter.
AD5045, AD5064, AD5064-1, AD5065, AD5628, AD5648, AD5666, AD5668 Digital
to Analog Converter.
To compile this driver as a module, choose M here: the
module will be called ad5064.
