iio: amplifiers: ada4250: add support for ADA4250

2022-02-27T12:06:25Z

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.

iio: Kconfig: ad8366: add entry for HMC1119 chip

2020-08-22T09:53:17Z

The change is mostly cosmetic. When looking into the menuconfig help of the ad8366 driver, the HMC1119 chip should also show up (since the driver supports it). Signed-off-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron

iio: amplifiers: hmc425a: Add support for HMC425A attenuator

2020-03-08T17:28:21Z

This patch adds support for the HMC425A 0.5 dB LSB GaAs MMIC 6-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, 2.2 - 8.0 GHz.

iio: amplifiers: ad8366: Add support for ADL5240 VGA

2019-06-17T20:06:48Z

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: ad8366: Add support for the ADA4961 DGA

2019-06-17T20:06:48Z

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. Signed-off-by: Paul Cercueil Signed-off-by: Michael Hennerich Signed-off-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron

iio: amplifiers: update license information

2019-06-17T20:06:47Z

Use the new `SPDX-License-Identifier` tag to specify the license. For ad8366, also update copyright years in the header part. Signed-off-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron

iio: Add a comment to about alphabetical order to Kconfigs and Makefiles

2013-08-03T17:40:36Z

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: New driver for AD8366 Dual-Digital Variable Gain Amplifier

2012-05-14T20:15:39Z

Changes since V1: Apply review feedback: Introduce and use IIO_CHAN_INFO_HARDWAREGAIN Introduce and use Use IIO_VAL_INT_PLUS_MICRO_DB Modify out of staging include paths. Convert to new iio core API naming. Changes since V2: more sanity checking in write_raw Signed-off-by: Michael Hennerich Acked-by: Jonathan Cameron Signed-off-by: Greg Kroah-Hartman
