AGL RH accelerometer does not provide IIO buffer

XMLWordPrintable

    • Renesas H3

      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.
