|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : should be one of
|
||
|
|
"adi,adxl345"
|
||
|
|
"adi,adxl375"
|
||
|
|
- 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>;
|
||
|
|
};
