Please update the binding file to describe the active level of the signal so people don't have to guess whether the sensor/driver is providing/expecting active low. See for example https://github.com/pabigot/zephyr/blob/286518ef1f79688524f7cc88d9073a1c95936de2/dts/bindings/sensor/st%2Chts221.yaml#L20

Generally we've been putting all changes related to the new API into a single commit, rather than breaking out the binding description from the driver support.

I can merge these both into a single commit, just wanted to see if the description was sufficient or not.

I merged them into one commit in the rebase.
