Sphinx reports two warnings on sysfs documentation for AD4130 driver:
Documentation/ABI/testing/sysfs-bus-iio-adc-ad4130:2: WARNING: Unexpected indentation.
Documentation/ABI/testing/sysfs-bus-iio-adc-ad4130:2: WARNING: Block quote ends without a blank line; unexpected unindent.
These are due to misformatting of sinc* modes list. Format it with bullet
list. Since each entry spans multiple lines, separate each with a blank
line.

Description:
|
|
Reading returns a list with the possible filter modes.
|
|
|
|
* "sinc4" - Sinc 4. Excellent noise performance. Long
|
|
1st conversion time. No natural 50/60Hz rejection.
|
|
|
|
* "sinc4+sinc1" - Sinc4 + averaging by 8. Low 1st conversion
|
|
time.
|
|
|
|
* "sinc3" - Sinc3. Moderate 1st conversion time.
|
|
Good noise performance.
|
|
|
|
* "sinc3+rej60" - Sinc3 + 60Hz rejection. At a sampling
|
|
frequency of 50Hz, achieves simultaneous 50Hz and 60Hz
|
|
rejection.
|
|
|
|
* "sinc3+sinc1" - Sinc3 + averaging by 8. Low 1st conversion
|
|
time. Best used with a sampling frequency of at least
|
|
216.19Hz.
|
|
|
|
* "sinc3+pf1" - Sinc3 + Post Filter 1. 53dB rejection @
|
|
50Hz, 58dB rejection @ 60Hz.
|
|
|
|
* "sinc3+pf2" - Sinc3 + Post Filter 2. 70dB rejection @
|
|
50Hz, 70dB rejection @ 60Hz.
|
|
|
|
* "sinc3+pf3" - Sinc3 + Post Filter 3. 99dB rejection @
|
|
50Hz, 103dB rejection @ 60Hz.
|
|
|
|
* "sinc3+pf4" - Sinc3 + Post Filter 4. 103dB rejection @
|
|
50Hz, 109dB rejection @ 60Hz.

Description:
|
|
Set the filter mode of the differential channel. When the filter
|
|
mode changes, the in_voltageY-voltageZ_sampling_frequency and
|
|
in_voltageY-voltageZ_sampling_frequency_available attributes
|
|
might also change to accommodate the new filter mode.
|
|
If the current sampling frequency is out of range for the new
|
|
filter mode, the sampling frequency will be changed to the
|
|
closest valid one.
