Well, this question was asked in the context of using a single IIO device for both accel / magnetometer. The user will open /dev/iio:deviceX and read accel/magnetometer samples. In the case were sampling frequency is the same for both devices everything is easy. The interesting case is the one when having a single IIO device with 2 channels (accel/magn) with different sampling rates. Anyhow, my implementation know uses 2 IIO devices and everything is clear.
