docs: iio: triggered-buffers: use new helpers in example

2026-05-31T10:01:46+00:00

Update the "typical" triggered buffer example to use various new helpers
that have been added in the last year or so. This reflects current
expectations of how similar code should be written.

Also zero-initialize the buffer so we don't leak stack data. And fix a
missing semicolon while we're at it.

Documentation: iio: fix typo in triggered-buffers example

2026-05-31T09:59:40+00:00

In the "IIO triggered buffer setup" example, iio_triggered_buffer_setup()
is called with "sensor_iio_polfunc" (single 'l') while the function is
defined and later referenced as "sensor_iio_pollfunc" (double 'l'). Fix
the misspelling so the example is consistent.

iio: ABI: Add support for floating-point numbers in buffer scan elements

2026-04-27T08:58:16+00:00

In the data storage description of a scan element, the first character
after the colon can have the values 's' and 'u' to specify signed and
unsigned integers, respectively.
Add 'f' as an allowed value to specify floating-point numbers formatted
according to the IEEE 754 standard.

iio: Replace 'sign' field with union in struct iio_scan_type

2026-04-27T08:58:16+00:00

This field is used to differentiate between signed and unsigned integers.
A following commit will extend its use in order to add support for non-
integer scan elements; therefore, replace it with a union that contains a
more generic 'format' field. This union will be dropped when all drivers
are changed to use the format field.
Opportunistically replace character literals with symbolic constants that
represent the set of allowed values for the format field.

docs: iio: fix bullet list formatting

2021-03-11T20:47:08+00:00

This 2nd-level bullet list is not properly ReST-formatted and thus it gets
rendered as a unique paragraph quite unreadable.  Fix by adding spaces as
needed.

While there also swap "shift" and "repeat" so they are in the correct
order.
