In the subject: Isn't the RM3100 a 3axis mag. The 9axis bit comes when you combine it with an accel / gryo I think.

Looking at other drivers supporting i2c / spi. They use the same compatible for both.
eg: see iio/accel/adxl345_*.c
and it's binding doc:
Required properties: - compatible : should be "adi,adxl345" - reg : the I2C address or SPI chip select number of the sensor
