Subject: [PATCH 1/3] dt-bindings: iio: pressure: Add Sensirion SDP500

Sensirion SDP500 is a digital differential pressure sensor. It provides
a digital I2C output. Add devicetree bindings requiring the compatible
string and I2C slave address (reg).

You should really fix the email flow on your side.

I see no mention of the sdp510 elsewhere in this patch though..
If you're trying to add support for both, then add a compatible for the
sdp510 that falls back to the sdp500.

Other than the fact that a fallback compatible might be required here,
this looks like a candidate for trivial-devices.yaml.

Fair point. Our focus is on the SDP500. SDP510 is the same software-wise so
I just mention it but I agree that I should add it as compatible in the code.

This sounds like a more serious comment. We will definitely continue using
this driver internally for now. But do you think it's still worth adding
it as a separate driver instead of leaving it for "trivial-devices"?
It has been a useful driver for us so we thought it is worth sharing.

trivial-devices.yaml is about the binding, not the driver - you still
get to have a dedicated driver.

This isn't in the binding that I can see.  It should be!
