On m41txx you can enable open-drain OUT pin to check if calibration is ok.
Enabling OUT pin with frequency-test bool property, OUT pin will tick
512 times faster than 1s tick base.

Enable FT bit on CONTROL register if calibration is active.

A DT is (or should be) a pretty static thing, so I don't think this
belongs. A kernel command line option (via module params) or a
sysfs/debugfs file would make more sense IMO.

Totally right, it's very useful having it accessible via sysfs.
Already changed and just submitted V2 patchset.
Thanks
