[PATCH 0/6] iio: adc: ad4080: add support for AD4083, AD4086, and AD4087
Posted by Antoniu Miclaus 3 months, 2 weeks ago
This patch series extends the AD4080 driver to support three additional
variants in the AD408x family of high-speed SAR ADCs: AD4083, AD4086,
and AD4087.

Each variant has different specifications that require separate driver
configurations:

- AD4083: 16-bit resolution, LVDS CNV clock count max = 5
- AD4086: 14-bit resolution, LVDS CNV clock count max = 4
- AD4087: 14-bit resolution, LVDS CNV clock count max = 1

The series follows a consistent pattern for each new device:
1. Add device tree binding support with appropriate compatible string
2. Implement driver support with chip-specific configuration

All new devices reuse the existing driver infrastructure established for
the AD4080/AD4081/AD4084 family, requiring only chip-specific channel
definitions and chip info structures.

The devices cannot use fallback compatible strings to the base AD4080
as they have significantly different resolutions and timing requirements
that necessitate distinct driver configurations.

Antoniu Miclaus (6):
  dt-bindings: iio: adc: adi,ad4080: add support for AD4083

I'd have been fine with this as 1 DT patch and 1 adding the support
given they are all pretty similar. Would have been slightly less work for
everyone ;)  Anyhow, not a big things so applied to the testing branch of
iio.git to let 0-day have a look before I push out as togreg to go into
linux-next.

Thanks
