+* Honeywell HMC5843 magnetometer sensor
+
+Required properties:
+
+ - compatible : should be "honeywell,hmc5843"
+ - reg : the I2C address of the magnetometer - typically 0x1e
+
+Optional properties:
+
+ - gpios : should be device tree identifier of the magnetometer DRDY pin
+
+Example:
+
+hmc5843@1e {
+ compatible = "honeywell,hmc5843"
+ reg = <0x1e>;
+};
