IIO buffers are used for data capture based on a trigger source: https://www.kernel.org/doc/html/latest/driver-api/iio/buffers.html
But it is not available for AGL RH
agl-refhw-h3:~# iio_readdev asm330lhh_accel Unable to allocate buffer: Invalid argument
and
agl-refhw-h3:/sys/bus/iio/devices/iio:device1# ls current_timestamp_clock in_accel_y_raw sampling_frequency dev in_accel_z_raw sampling_frequency_available in_accel_scale name subsystem in_accel_scale_available of_node uevent in_accel_x_raw power
I have tracked down that st_lsm6dsx_probe is called with irq=0, so this sounds for me like DTS misconfiguration.
