[PATCH v2 0/2] iio: temperature: tmp117: Support the TMP119 sensor

[PATCH v2 0/2] iio: temperature: tmp117: Support the TMP119 sensor

[Romain Gantois]

Hello everyone,

This is version two of my series which adds support for the TMP119, which has
an identical programming model to the TMP117, but slightly different specs and
electrical characteristics.

Best Regards,

Romain

Changes in v2:
- Used ti,tmp117 as a fallback compatible
- Made sure the correct IIO device name was exposed to userspace
- Link to v1: https://patch.msgid.link/20260605-tmp119-v1-0-349f45f17d12@bootlin.com

[PATCH v2 1/2] dt-bindings: iio: ti,tmp117: add binding for the TMP119

[Romain Gantois]

The TMP119 has the same register layout as the TMP117, and a better local
sensor accuracy. Add a compatible for it.

Use ti,tmp117 as a fallback compatible for ti,tmp119.

Indent here looks undersized, is that just the diff being weird?

It's not just the diff. Testing the binding would show you what's wrong.

See https://patchwork.kernel.org/project/devicetree/patch/20260608-tmp119-v2-1-30c3537d5097@bootlin.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

Hi Romain

Other than the DT indent thing Conor calls out this looks fine to me.
However, unless the cycle is extended IIO is effectively closed for this
kernel cycle. Anything I queue up now will be targeting 7.3 now.
On the plus side no rush for v3!

Thanks,

Jonathan
