Thanks for going through the code. I didn't notice the ICM42607 in the
mailing list. I will add support for ICM42370 to that driver instead of
creating a new driver. I will have a patchset for basic support and
then incremental patches for implementing more features (like buffer).

Thanks and Regards,
