2022-02-27iio: amplifiers: ada4250: add support for ADA4250Antoniu Miclaus1-0/+1
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.

2013-08-03iio: Add a comment to about alphabetical order to Kconfigs and MakefilesLars-Peter Clausen1-0/+1
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.
