The get_frame_count() API must return the number of frames in FIFO for a given channel type, and not the total number of generic FIFO frames. This API may be also re-used in the decoder routine when the timestamp baseline is adjusted. Signed-off-by: Armando Visconti <[email protected]>

Add sample to read from up to 10 FIFO streaming devices, using the
sensor_stream() API and the RTIO framework:
https://docs.zephyrproject.org/latest/services/rtio/index.html
The devices has to be aliased as streamN (0 <= N <= 9) in DT, and
will be instantiated using SENSOR_DT_STREAM_IODEV() macro.
Currently the sample gets/prints data on SENSOR_TRIG_FIFO_WATERMARK
trigger basis for the following sensor channels:
- SENSOR_CHAN_ACCEL_XYZ
- SENSOR_CHAN_GYRO_XYZ
- SENSOR_CHAN_DIE_TEMP

Tested with the lsm6dsv16x sensor on a nucleo_h503rb board and a x_nucleo_iks4a1 shield (I2C bus).
EDIT:
The idea is to extend it with the capability of reading other (virtual) sensors, including the GAME_ROTATION Vector quaternions from FIFO.
