0015 Say yes here to build support for Analog Devices AD8366 and similar
0016 gain amplifiers. This driver supports the following gain amplifiers
0017 from Analog Devices:
0018 AD8366 Dual-Digital Variable Gain Amplifier (VGA)
0019 ADA4961 BiCMOS RF Digital Gain Amplifier (DGA)
0020 ADL5240 Digitally controlled variable gain amplifier (VGA)
0021 HMC1119 0.25 dB LSB, 7-Bit, Silicon Digital Attenuator

0023 To compile this driver as a module, choose M here: the
0024 module will be called ad8366.
