Hi,
Any specific reason to why the 12.5Hz sample rate is implemented as 13Hz ?

Hi Sean,
what is the device you are referring to? I guess now all devices support
12.5Hz.

At least the two devices we are using.
ISM330DLC and LSM6DSLTR, they do not support 13Hz sampling rate, but 12.5Hz.
I think we should expose the correct 12.5Hz to user space.
Should do a patch? (It could potentially break some implementations)
