[PATCH] dt-bindings: iio: adc: Add AD7816 binding

[Omer PALA]

Add a DeviceTree binding schema for the Analog Devices AD7816
digital temperature sensor. The same schema also covers the
compatible AD7817 and AD7818 variants.

The driver currently lives under drivers/staging/iio/adc/ad7816.c.

Then why are you posting this? Did you read discussions I linked before?
If so, why repeating the same?

Best regards,
Krzysztof

Hi Krzysztof,

You are completely right, and I apologize for missing this. I will
drop this patch since the driver is still under staging.

Thank you for your guidance and patience.

Sorry for wasting your time.

Best regards,
Omer PALA
