| 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>; |
| }; |
