dt-bindings: iio: amplifiers: add adl8113

2025-12-21T11:41:13Z

Add devicetree bindings for the ADL8113 Low Noise Amplifier. The bindings include support for specifying gain values of external amplifiers connected to the two external bypass paths (A and B). These optional properties allow the gain values to be selectable via the hardwaregain attribute, enabling complete devicetree description of the signal chain including external components.

dt-bindings: iio: hmc425a: add conditional GPIO array size constraints

2024-02-28T19:26:35Z

ADRF5740 and HMC540S have a 4 bit parallel interface. Update ctrl-gpios description and min/maxItems values depending on the matched compatible to correctly reflect the hardware properties.

dt-bindings: iio: amplifiers: adi,ada4250: use spi-peripheral-props.yaml

2022-08-19T18:34:16Z

Instead of listing directly properties typical for SPI peripherals, reference the spi-peripheral-props.yaml schema. This allows using all properties typical for SPI-connected devices, even these which device bindings author did not tried yet. Remove the spi-* properties which now come via spi-peripheral-props.yaml schema, except for the cases when device schema adds some constraints like maximum frequency. While changing additionalProperties->unevaluatedProperties, put it in typical place, just before example DTS.

dt-bindings: Another round of adding missing 'additionalProperties'

2020-10-06T15:55:25Z

Another round of wack-a-mole. The json-schema default is additional unknown properties are allowed, but for DT all properties should be defined.

dt-bindings: Whitespace clean-ups in schema files

2020-08-14T14:55:58Z

Clean-up incorrect indentation, extra spaces, long lines, and missing EOF newline in schema files. Most of the clean-ups are for list indentation which should always be 2 spaces more than the preceding keyword. Found with yamllint (which I plan to integrate into the checks).
