* 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 */
"0", /* x1 */
"-1", /* y1 */
"0", /* z1 */
"-0.173648177666930", /* x2 */
"0", /* y2 */
"0.984807753012208"; /* z2 */
};
