Required properties:

- - compatible : should be "asahi-kasei,ak8975"
- - reg : the I2C address of the magnetometer
+ - compatible : should be "asahi-kasei,ak8975".
+ - reg : the I2C address of the magnetometer.

Optional properties:

- - gpios : should be device tree identifier of the magnetometer DRDY pin
- - vdd-supply: an optional regulator that needs to be on to provide VDD
- - mount-matrix: an optional 3x3 mounting rotation matrix
+ - gpios : AK8975 has a "Data ready" pin (DRDY) which informs that data
+ is ready to be read and is possible to listen on it. If used,
+ this should be active high. Prefer interrupt over this.
+
+ - interrupts : interrupt for DRDY pin. Triggered on rising edge.
+
+ - vdd-supply: an optional regulator that needs to be on to provide VDD.
+
+ - mount-matrix: an optional 3x3 mounting rotation matrix.

Example:

ak8975@c {
compatible = "asahi-kasei,ak8975";
reg = <0x0c>;
- gpios = <&gpj0 7 0>;
+ interrupt-parent = <&gpio6>;
+ interrupts = <15 IRQ_TYPE_EDGE_RISING>;
vdd-supply = <&ldo_3v3_gnss>;
mount-matrix = "-0.984807753012208", /* x0 */
"0", /* y0 */
