+ Say yes here to build support for Analog Devices AD8366 and similar
+ gain amplifiers. This driver supports the following gain amplifiers
+ from Analog Devices:
+ AD8366 Dual-Digital Variable Gain Amplifier (VGA)
+ ADA4961 BiCMOS RF Digital Gain Amplifier (DGA)
+ ADL5240 Digitally controlled variable gain amplifier (VGA)
+ HMC792A 0.25 dB LSB GaAs MMIC 6-Bit Digital Attenuator
+ HMC1119 0.25 dB LSB, 7-Bit, Silicon Digital Attenuator
+
+ To compile this driver as a module, choose M here: the
+ module will be called ad8366.
