From: Li peiyu <579lpy@xxxxxxxxx> Add device tree bindings for HDC3020/HDC3021/HDC3022 humidity and temperature sensors. Signed-off-by: Li peiyu <579lpy@xxxxxxxxx> --- changes for v3: - Use a fallback compatible changes for v2: - change the maintainers to me. - hdc3020,hdc3021,hdc3022 are compatible,I've changed the dirver. - change the node name to humidity-sensor. .../bindings/iio/humidity/ti,hdc3020.yaml | 63 +++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/humidity/ti,hdc3020.yaml diff --git a/Documentation/devicetree/bindings/iio/humidity/ti,hdc3020.yaml b/Documentation/devicetree/bindings/iio/humidity/ti,hdc3020.yaml new file mode 100644 index 000000000000..08080bb9cd75 --- /dev/null +++ b/Documentation/devicetree/bindings/iio/humidity/ti,hdc3020.yaml @@ -0,0 +1,63 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/iio/humidity/ti,hdc3020.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: HDC3020/HDC3021/HDC3022 humidity and temperature iio sensors + +maintainers: + - Li peiyu <579lpy@xxxxxxxxx> + +description: + https://www.ti.com/lit/ds/symlink/hdc3020.pdf + + The HDC302x is an integrated capacitive based relative humidity (RH) + and temperature sensor. + +properties: + compatible: + oneOf: + - items: + - enum: + - ti,hdc3021 + - ti,hdc3022 + - const: ti,hdc3020 + - items: + - const: ti,hdc3020 + + interrupts: + maxItems: 1 + + vdd-supply: true + + reg: + maxItems: 1 + +required: + - compatible + - reg + +additionalProperties: false + +examples: + - | + i2c { + #address-cells = <1>; + #size-cells = <0>; + + humidity-sensor@47 { + compatible = "ti,hdc3020"; + reg = <0x47>; + }; + }; + - | + i2c { + #address-cells = <1>; + #size-cells = <0>; + + humidity-sensor@47 { + compatible = "ti,hdc3021", "ti,hdc3020"; + reg = <0x47>; + }; + }; -- 2.34.1
