-* AsahiKASEI AK8975 magnetometer sensor
-
-Required properties:
-
- - compatible : should be "asahi-kasei,ak8975".
- - reg : the I2C address of the magnetometer.
-
-Optional properties:
-
- - 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>;
- interrupt-parent = <&gpio6>;
- interrupts = <15 IRQ_TYPE_EDGE_RISING>;
- vdd-supply = <&ldo_3v3_gnss>;
- mount-matrix = "-0.984807753012208", /* x0 */
- "0", /* y0 */
- "-0.173648177666930", /* z0 */
