+* 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
+
+Example:
+
+ak8975@0c {
+ compatible = "asahi-kasei,ak8975";
+ reg = <0x0c>;
+ gpios = <&gpj0 7 0>;
+};
