PNI RM3100 is a high resolution, large signal immunity magnetometer,
composed of 3 single sensors and a processing chip with a MagI2C
interface.
Following functions are available:
- Single-shot measurement from
/sys/bus/iio/devices/iio:deviceX/in_magn_{axis}_raw
- Triggerd buffer measurement.
- DRDY pin for data ready trigger.
- Both i2c and spi interface are supported.
