* Add new `steps` property to the `aips,ec11` binding, to make
the driver properly report degrees in the rotation delta channel.
* Handle old sensor values in sensor rotate behavior.
* Move away from DT_LABEL.
* Move to DEVICE_DT_GET for non-behavior device access.
* Move various drivers to `gpio_spec_dt` and `DT` related macros.

available.
