Kernel-4.18.0-80.el8_adxl345

Analog Devices ADXL345 3-Axis, +/-(2g/4g/8g/16g) Digital Accelerometer

http://www.analog.com/en/products/mems/accelerometers/adxl345.html

Required properties:

  • compatible : should be “adi,adxl345”
  • reg : the I2C address or SPI chip select number of the sensor

Required properties for SPI bus usage:

  • spi-max-frequency : set maximum clock frequency, must be 5000000
  • spi-cpol and spi-cpha : must be defined for adxl345 to enable SPI mode 3

Optional properties:

  • interrupt-parent : phandle to the parent interrupt controller as documented
    in Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
  • interrupts: interrupt mapping for IRQ as documented in
    Documentation/devicetree/bindings/interrupt-controller/interrupts.txt

Example for a I2C device node:

accelerometer@2a {
    compatible = "adi,adxl345";
    reg = <0x53>;
    interrupt-parent = <&gpio1>;
    interrupts = <0 IRQ_TYPE_LEVEL_HIGH>;
};

Example for a SPI device node:

accelerometer@0 {
    compatible = "adi,adxl345";
    reg = <0>;
    spi-max-frequency = <5000000>;
    spi-cpol;
    spi-cpha;
    interrupt-parent = <&gpio1>;
    interrupts = <0 IRQ_TYPE_LEVEL_HIGH>;
};
