Kernel-4.18.0-80.el8_ak8974

  • Asahi Kasei AK8974 magnetometer sensor

Required properties:

  • compatible : should be “asahi-kasei,ak8974”
  • 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>;
};
