While developing this driver, we glossed over AD7389-4 since we didn't have hardware to test it. However, it should be trivial enough to add support without testing. It is basically the same as AD7380-4 but instead of no internal reference, it has no external reference. And we already have support for chips with internal reference only (ADAQ). We have the typical DT bindings/driver/documentation patches for it plus a few patches to shuffle around the existing code for supporting chips with internal-reference-only to make it generic enough to support this chip as well. --- David Lechner (5): dt-bindings: iio: adc: ad7380: add AD7389-4 iio: adc: ad7380: rename internal_ref_only iio: adc: ad7380: move internal reference voltage to chip_info iio: adc: ad7380: add ad7389-4 Documentation: iio: ad7380: add AD7389-4 .../devicetree/bindings/iio/adc/adi,ad7380.yaml | 11 +++++ Documentation/iio/ad7380.rst | 7 +++ drivers/iio/adc/ad7380.c | 50 +++++++++++++++++++--- 3 files changed, 61 insertions(+), 7 deletions(-) --- base-commit: f8ffc92ae9052e6615896052f0c5b808bfc17520 change-id: 20250401-iio-ad7380-add-ad7389-4-1f6d3d7dc749 Best regards, -- David Lechner <dlechner@xxxxxxxxxxxx>
