[RFC PATCH 1/7] iio:ABI docs: Fix up duplicate *_calibbias_* documentation for icm42600

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>

This device has the unusual characteristic that the calibbias values
have well defined units (more commonly they are tweaks to a DAC)
Unfortunately the previous approach of having more specific documentation
in sysfs-bus-iio-icm42600 results in warnings during the documentation
build and random ordering in the resulting documentation.

To avoid this, add a note to the main documentation on this special
characteristic for the icm42600.   The _available for calibbias was
missing from the main sysfs-bus-iio docs so also add that, allowing
us to drop the icm42600 specific file.
