Hello Jonathan, no problem for me, you can move it wherever you see fit. Thank you.

This is causing us some issues as the ABI docs are now added to the generated html docs for the kernel. It's been a while, so I've kind of forgotten why we have this file. Was the issue that these are in SI units as opposed to most calibbias controls which are offsets applied to the raw analog reading hitting the ADC? Would you mind if we moved this into the main doc as a note for this particular device? i.e. something in sysfs-bus-iio saying icm42600: Hardware applied calibration offset is in SI units (rad/s or m/s^2 as appropriate) ?
