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>;

	};
