[PATCH v3 1/3] dt-bindings: iio: chemical: Document senseair,sunrise CO2 sensor

[PATCH v3 1/3] dt-bindings: iio: chemical: Document senseair,sunrise CO2 sensor

[Jacopo Mondi]

Add documentation for the Senseair Sunrise 006-0-0007 CO2 NDIR sensor.

Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>
---
v2->v3:
- Fix syntax error reported by dt_binding_check
  The device node label in the example cannot contain '-'
- Add 'Typically' to the gpios polarities description

v1->v2:
- Add maxItems to -gpios properties as suggested by Rob
- Add a label to the device node in the example as suggested by Rob
