Required properties:
|
|
|
|
- compatible : should be one of:
|
|
"bosch,bma023"
|
|
"bosch,bma150"
|
|
"bosch,bma180"
|
|
"bosch,bma250"
|
|
"bosch,bma254"
|
|
"bosch,smb380"
|
|
- reg : the I2C address of the sensor
|
|
- vdd-supply : regulator phandle connected to the VDD pin
|
|
- vddio-supply : regulator phandle connected to the VDDIO pin
|
|
|
|
Optional properties:
|
|
|
|
- interrupts : interrupt mapping for GPIO IRQ, it should by configured with
|
|
flags IRQ_TYPE_LEVEL_HIGH | IRQ_TYPE_EDGE_RISING
|
|
For the bma250 the first interrupt listed must be the one
|
|
connected to the INT1 pin, the second (optional) interrupt
|
|
listed must be the one connected to the INT2 pin.
|
|
|
|
Example:
|
|
|
|
bma180@40 {
|
|
compatible = "bosch,bma180";
|
|
reg = <0x40>;
|
|
interrupt-parent = <&gpio6>;
|
|
interrupts = <18 (IRQ_TYPE_LEVEL_HIGH | IRQ_TYPE_EDGE_RISING)>;
|
|
};
