* 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>;
};
