/**
* struct st_sensors_platform_data - Platform data for the ST sensors
* @drdy_int_pin: Redirect DRDY on pin 1 (1) or pin 2 (2).
- * Available only for accelerometer and pressure sensors.
+ * Available only for accelerometer, magnetometer and pressure sensors.
* Accelerometer DRDY on LSM330 available only on pin 1 (see datasheet).
+ * Magnetometer DRDY is supported only on LSM9DS0.
* @open_drain: set the interrupt line to be open drain if possible.
* @spi_3wire: enable spi-3wire mode.
* @pullups: enable/disable i2c controller pullup resistors.
Provide default platform data for magnetometer in case it supports DRDY. One case is LSM9DS0 IMU, on which it is the case. Since accelerometer is using INT1, default magnetometer to INT2. While at it, update description of the drdy_int_pin field.
