There's already an ABI documentation for this driver.
See:
https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio.git/tree/drivers/staging/iio/Documentation/sysfs-bus-iio-impedance-analyzer-ad5933

Apologies for not mentioning this sooner.

Could you check for other references for ad5933 in the kernel (in staging) ?
I don't think I missed other stuff, but it's good to check.
