Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

	select BITREVERSE
	help
	  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)
	    ADRF5702: 0.125 dB LSB, 8-Bit, Silicon Digital Attenuator
	    ADRF5703: 0.25 dB LSB, 7-Bit, Silicon Digital Attenuator
	    ADRF5720: 0.5 dB LSB, 6-Bit, Silicon Digital Attenuator
	    ADRF5730: 0.5 dB LSB, 6-Bit, Silicon Digital Attenuator
	    ADRF5731: 2 dB LSB, 4-Bit, Silicon Digital Attenuator
	    HMC271A: 1dB LSB 5-Bit Digital Attenuator SMT
	    HMC792A 0.25 dB LSB GaAs MMIC 6-Bit Digital Attenuator
	    HMC1018A: 1.0 dB LSB GaAs MMIC 5-BIT Digital Attenuator
	    HMC1019A: 0.5 dB LSB GaAs MMIC 5-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.

config ADA4250
	tristate "Analog Devices ADA4250 Instrumentation Amplifier"
	depends on SPI
	select REGMAP_SPI
	help
	  Say yes here to build support for Analog Devices ADA4250
	  SPI Amplifier's support. The driver provides direct access via
	  sysfs.

	  To compile this driver as a module, choose M here: the
	  module will be called ada4250.

config ADL8113
	tristate "Analog Devices ADL8113 Low Noise Amplifier"
	depends on GPIOLIB
	help
	  Say yes here to build support for Analog Devices ADL8113 Low Noise
	  Amplifier with integrated bypass switches. The device supports four
	  operation modes controlled by GPIO pins: internal amplifier,
	  internal bypass, and two external bypass modes.

	  To compile this driver as a module, choose M here: the
	  module will be called adl8113.

config HMC425
	tristate "Analog Devices HMC425A and similar GPIO Gain Amplifiers"
	depends on GPIOLIB
	help
	  Say yes here to build support for Analog Devices HMC425A and similar
	  gain amplifiers or step attenuators.

	  To compile this driver as a module, choose M here: the
	  module will be called hmc425a.

Atlas domain: Driver Families / drivers/iio.
Implementation status: atlas-only.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
