st_lsm6dsx minor issue

[Okba Slatnia]

Hi all,

I'm building a yocto firmware based on Linux kernel version 5.15.148
and i'm facing a little limitation or problem preventing me from
changing the value of the sampling_frequency of the accelerator:
/sys/bus/iio/devices/iio:device0/sampling_frequency
despite i'm following the
/sys/bus/iio/devices/iio:device0/sampling_frequenc_available for the
possible values.
for the info , i can successfully change the sampling_frequency on
another yocto firmware based on Linux kernel version 4.19 and despite
keeping the same kernel flags confs i'm still facing this issue , i
made sure it's not an access right issue because i can change other
files in the same path with same access rights.

Can you please help me and tell me if I missed anything ?
Thanks in advance.
Best Regards.

Can you please provide more details about the issue? Are you able to change
gyro sample frequency? Is the sensor-hub enabled?
