* Asahi Kasei AK8974 magnetometer sensor
|
|
|
|
Required properties:
|
|
|
|
- compatible:
|
|
* "asahi-kasei,ak8974"
|
|
* "alps,hscdtd008a"
|
|
- reg : the I2C address of the magnetometer
|
|
|
|
Optional properties:
|
|
|
|
- avdd-supply: regulator supply for the analog voltage
|
|
(see regulator/regulator.txt)
|
|
- dvdd-supply: regulator supply for the digital voltage
|
|
(see regulator/regulator.txt)
|
|
- interrupts: data ready (DRDY) and interrupt (INT1) lines
|
|
from the chip, the DRDY interrupt must be placed first.
|
|
The interrupts can be triggered on rising or falling
|
|
edges alike.
|
|
- mount-matrix: an optional 3x3 mounting rotation matrix
|
|
|
|
Example:
|
|
|
|
ak8974@f {
|
|
compatible = "asahi-kasei,ak8974";
|
|
reg = <0x0f>;
|
|
avdd-supply = <&foo_reg>;
|
|
dvdd-supply = <&bar_reg>;
|
|
interrupts = <0 IRQ_TYPE_EDGE_RISING>,
|
|
<1 IRQ_TYPE_EDGE_RISING>;
|
|
};
