dt-bindings: iio: amplifiers: ad8366: add adrf5702/3 support

2026-03-26T20:10:26+00:00

Add compatible entries for ADRF5702 and ADRF5703 Digital Attenuators.
ADRF5702 is an 8-bit DSA with a step of 0.125 dB and ADRF5703 is a 7-bit
DSA with a step 0.25 dB. Then, each device ends up with its own gain
range, hence no fallback compatibles are used.

dt-bindings: iio: adc: amlogic,meson-saradc: add S4 compatible

2026-03-26T19:56:43+00:00

Add the compatible string for the SARADC (Successive Approximation
Register ADC) IP block found in the Amlogic Meson S4 SoC.

There are no known differences between the SARADC on S4 and the one
on G12A. Therefore, it uses "amlogic,meson-g12a-saradc" as a proper
specific fallback.

Also add a comment indicating that "amlogic,meson-saradc" must not be
used for new devices. It's a made up compatible string that does not
correspond to a specific hardware generation and is not used to match
any driver. For old devices we keep it as it's part of the ABI.

dt-bindings: iio: proximity: add ST VL53L1X ToF sensor

2026-03-26T08:20:51+00:00

Add device tree binding documentation for the STMicroelectronics
VL53L1X Time-of-Flight ranging sensor connected via I2C.

vdd-supply is not made globally required to maintain backwards
compatibility with existing st,vl53l0x devicetrees that do not specify it.

dt-bindings: adc: ltc2497: add support for ltc2305

2026-03-25T19:48:45+00:00

Add documentation for the 2-channel LTC2305 ADC in the
existing ltc2497 binding.
This enables automatic device tree matching for LTC2305
while using the LTC2309 driver (drivers/iio/adc/ltc2309.c),
since both ADCs share the same I2C interface and 12-bit SAR architecture.
The main difference is the number of channels (LTC2305: 2, LTC2309: 8).

dt-bindings: iio: dac: maxim,ds4424: add maxim,rfs-ohms property

2026-03-22T12:44:23+00:00

The Maxim DS4422/DS4424 and DS4402/DS4404 current DACs determine their
full-scale output current via external resistors (Rfs) connected to the
FSx pins. Without knowing these values, the full-scale range of the
hardware is undefined.

Add the 'maxim,rfs-ohms' property to describe these physical components.
This property is required to provide a complete description of the
hardware configuration.

Add compatible strings for Maxim DS4402 and DS4404 current DACs.
These devices are 5-bit variants of the DS4422/DS4424 family.

dt-bindings: iio: dac: ltc2632: add LTC2654 compatible strings

2026-03-21T15:39:00+00:00

Add compatible strings for the LTC2654 quad-channel DAC family.

The LTC2654 devices are 4-channel, 16-/12-bit DACs with an internal
reference and SPI interface. They use the same 24-bit SPI command
format as the LTC2632/2634/2636 family.

The 16-bit variants (LTC2654-L16 and LTC2654-H16) require new
compatible strings, as no existing compatibles support 16-bit
resolution.

The 12-bit variants (LTC2654-L12 and LTC2654-H12) are register-
compatible with LTC2634-L12 and LTC2634-H12 respectively, and can
use them as fallback compatibles.

dt-bindings: iio: light: vcnl4000: add regulators

2026-03-21T12:40:19+00:00

These sensors can accept 2 supplies - one for the sensor and one for IR
LED [1]. Add supply properties for the sensor - 2 for the sensors and
one external, for their open drain interrupt line, to ensure the sensor
is powered on before proceeding with setup.

dt-bindings: iio: accel: adi,adxl372: add ADXL371 compatible

2026-03-21T11:20:58+00:00

Add the adi,adxl371 compatible string to the ADXL372 binding. The
ADXL371 is a +-200g 3-axis MEMS accelerometer nearly identical to
the ADXL372 in register layout, differing only in ODR/bandwidth
values, timer scale factors, and a silicon anomaly affecting FIFO
operation.

Update the title and description to reflect both devices.
