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: - 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>; };
