iio: Add a comment to about alphabetical order to Kconfigs and Makefiles Keeping Makefile and Kconfig entries in alphabetical order usually works better than just appending new entries at the end, since it reduces the amount of conflicts. This patch adds a comment to the IIO Kconfig and Makefile files to document that the entries should be kept in alphabetical order. Also reorder those entries which weren't in alphabetical order yet.

iio: amplifiers: ad8366: Add support for the ADA4961 DGA This change adds support for the ADA4961 BiCMOS RF Digital Gain Amplifier, (DGA), which is optimized for driving heavy loads out 2.0 GHz and beyond. The device typically achieves -90 dBc IMD3 performance at 500 MHz and -85 dBc at 1.5 GHz. Datasheet link: http://www.analog.com/media/en/technical-documentation/data-sheets/ADA4961.pdf This change re-uses the existing ad8366 driver, as most logic is similar. Also, this chip has a reset pin which is initialized during probe.

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)
iio: amplifiers: ad8366: Add support for ADL5240 VGA The ADL5240 is a high performance, digitally controlled variable gain amplifier (VGA) operating from 100 MHz to 4000 MHz. The VGA integrates a high performance, 20 dB gain, internally matched amplifier (AMP) with a 6-bit digital step attenuator (DSA) that has a gain control range of 31.5 dB in 0.5 dB steps with ±0.25 dB step accuracy.

iio: amplifiers: ada4250: add support for ADA4250 The ADA4250 is an instrumentation amplifier with SPI/pin-strap progammable gains that is optimized for ultra-low power systems. With a minimum supply voltage of 1.7V, 26uA of quiescent current, a shutdown mode, a sleep mode, and a fast wake up settling time, ADA4250 can be power cycled on a battery powered system for even futher savings.
