The ADXL380 + supports the ±4 g, ±8 g, and ±16 g ranges, and the ADXL382 supports + ±15 g, ±30 g, and ±60 g ranges. + The ADXL380/ADXL382 offers industry leading noise, enabling precision + applications with minimal calibration. The low noise, and low power + ADXL380/ADXL382 enables accurate measurement in an environment with + high vibration, heart sounds and audio. + + In addition to its low power consumption, the ADXL380/ADXL382 has + many features to enable true system level performance.

In addition, the ADXL380/ADXL382 has provisions for + external control of the sampling time and/or an external clock. + + https://www.analog.com/en/products/adxl380.html + +properties: + compatible: + enum: + - adi,adxl380 + - adi,adxl382 + + reg: + maxItems: 1 + + interrupts: + minItems: 1 + maxItems: 2 + + interrupt-names: + minItems: 1 + items: + - enum: [INT0, INT1] + - const: INT1 + + vddio-supply: true + + vsupply-supply: true + +required: + - compatible + - reg + - interrupts + - interrupt-names + - vddio-supply + - vsupply-supply + +allOf: + - $ref: /schemas/spi/spi-peripheral-props.yaml# + +unevaluatedProperties: false + +examples: + - | + #include <dt-bindings/interrupt-controller/irq.h> + + i2c { + #address-cells = <1>; + #size-cells = <0>; + + accelerometer@54 { + compatible = "adi,adxl380"; + reg = <0x54>; + vddio-supply = <&vddio>; + vsupply-supply = <&vsupply>; + interrupt-parent = <&gpio>; + interrupts = <25 IRQ_TYPE_LEVEL_HIGH>; + interrupt-names = "INT0"; + }; + }; + - | + #include <dt-bindings/interrupt-controller/irq.h> + + spi { + #address-cells = <1>; + #size-cells = <0>; + + accelerometer@0 { + compatible = "adi,adxl380"; + reg = <0>; + spi-max-frequency = <8000000>; + vddio-supply = <&vddio>; + vsupply-supply = <&vsupply>; + interrupt-parent = <&gpio>; + interrupts = <25 IRQ_TYPE_LEVEL_HIGH>; + interrupt-names = "INT0"; + }; + }; diff --git a/MAINTAINERS b/MAINTAINERS index be590c462d91..1425182c85e2 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -618,6 +618,13 @@ F: drivers/iio/accel/adxl372.c F: drivers/iio/accel/adxl372_i2c.c F: drivers/iio/accel/adxl372_spi.c +ADXL380 THREE-AXIS DIGITAL ACCELEROMETER DRIVER +M: Ramona Gradinariu <ramona.gradinariu@xxxxxxxxxx> +M: Antoniu Miclaus <antoniu.miclaus@xxxxxxxxxx> +S: Supported +W: https://ez.analog.com/linux-software-drivers +F: Documentation/devicetree/bindings/iio/accel/adi,adxl380.yaml + AF8133J THREE-AXIS MAGNETOMETER DRIVER M: Ondřej Jirman <megi@xxxxxx> S: Maintained -- 2.45.2
