Documentation: ABI: IIO: add new convdelay documentation

Browse Source 
Add new IIO "convdelay" documentation.

The ad7606 implements a phase calibation feature, in nanoseconds.
Being this a time delay, using the convdelay suffix.

@ -559,6 +559,30 @@ Description:
- a small discrete set of values like "0 2 4 6 8"
- a range specified as "[min step max]"
What: /sys/bus/iio/devices/iio:deviceX/in_voltageY_convdelay
KernelVersion: 6.17
Contact: linux-iio@vger.kernel.org
Description:
Delay of start of conversion from common reference point shared
by all channels. Can be writable when used to compensate for
delay variation introduced by external filters feeding a
simultaneous sampling ADC.
E.g., for the ad7606 ADC series, this value is intended as a
configurable time delay in seconds, to correct delay introduced
by an optional external filtering circuit.
What: /sys/bus/iio/devices/iio:deviceX/in_voltageY_convdelay_available
KernelVersion: 6.16
Contact: linux-iio@vger.kernel.org
Description:
Available values of convdelay. Maybe expressed as:
- a range specified as "[min step max]"
If shared across all channels, <type>_convdelay_available
is used.
