Subject: [PATCH v6 4/4] dt-bindings: iio: humidity: Add TI HDC302x support
Add device tree bindings for HDC3020/HDC3021/HDC3022 humidity and
temperature sensors.
Signed-off-by: Li peiyu <579lpy@...il.com>
---
changes in v6:
- remove items before "- const: ti,hdc3020".
- add vdd-supply to required.
changes in v4:
- removed unnecessary example.
- add vdd-supply to the example.
changes in v3:
- Use a fallback compatible.
changes in v2:
- change the maintainers to me.
- hdc3020,hdc3021,hdc3022 are compatible,I've changed the dirver.
- change the node name to humidity-sensor.
