-* AsahiKASEI AK8975 magnetometer sensor
-
-Required properties:
-
-  - 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
-
-Example:
-
-ak8975@c {
-        compatible = "asahi-kasei,ak8975";
-        reg = <0x0c>;
-        gpios = <&gpj0 7 0>;
