Add bindings for ScioSense ENS160 multi-gas sensor. Datasheet: https://www.sciosense.com/wp-content/uploads/2023/12/ENS160-Datasheet.pdf Signed-off-by: Gustavo Silva <gustavograzs@xxxxxxxxx> --- changes in v2: - Add devicetree binding file specifically for this sensor instead of adding it to trivial-devices.yaml. This is needed in order to document that this chip supports Vdd and Vddio supplies. .../iio/chemical/sciosense,ens160.yaml | 68 +++++++++++++++++++ 1 file changed, 68 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/chemical/sciosense,ens160.yaml diff --git a/Documentation/devicetree/bindings/iio/chemical/sciosense,ens160.yaml b/Documentation/devicetree/bindings/iio/chemical/sciosense,ens160.yaml new file mode 100644 index 000000000..7dd442f94 --- /dev/null +++ b/Documentation/devicetree/bindings/iio/chemical/sciosense,ens160.yaml @@ -0,0 +1,68 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/iio/chemical/sciosense,ens160.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: ScioSense ENS160 multi-gas sensor + +maintainers: + - Gustavo Silva <gustavograzs@xxxxxxxxx> + +description: | + Digital Multi-Gas Sensor for Monitoring Indoor Air Quality. + + Datasheet: + https://www.sciosense.com/wp-content/uploads/2023/12/ENS160-Datasheet.pdf + +properties: + compatible: + enum: + - sciosense,ens160 + + reg: + maxItems: 1 + + interrupts: + maxItems: 1 + + vdd-supply: true + vddio-supply: true + +required: + - compatible + - reg + +additionalProperties: false + +examples: + - | + #include <dt-bindings/interrupt-controller/irq.h> + i2c { + #address-cells = <1>; + #size-cells = <0>; + + gas-sensor@52 { + compatible = "sciosense,ens160"; + reg = <0x52>; + interrupt-parent = <&gpio0>; + interrupts = <19 IRQ_TYPE_EDGE_FALLING>; + }; + }; + - | + #include <dt-bindings/interrupt-controller/irq.h> + + spi { + #address-cells = <1>; + #size-cells = <0>; + + gas-sensor@0 { + compatible = "sciosense,ens160"; + reg = <0>; + spi-max-frequency = <10000000>; + interrupt-parent = <&gpio>; + interrupts = <19 IRQ_TYPE_EDGE_FALLING>; + }; + }; + +... -- 2.45.1
