This is a v2 & v3 for [1]:
https://lore.kernel.org/linux-iio/20200925083743.46469-1-alexandru.ardelean@analog.com/

It also includes a at91-sama5d2_adc cleanup patch in this series:
https://lore.kernel.org/linux-iio/20200924102902.136169-1-alexandru.ardelean@analog.com/
This patch is required, in order to make the removal of
iio_buffer_set_attrs() a bit cleaner in the at91-sama5d2_adc driver.

Following the discussion from [1], this patchset implements the
following:

Changelog v2 -> v3:
* in patch 'iio: buffer: dmaengine: unwrap the use of iio_buffer_set_attrs()'
- minor stylistic change;

Changelog v1 -> v2:
* rename '{devm_}iio_triggered_buffer_setup()' ->
'{devm_}iio_triggered_buffer_setup_ext()'
- wrap with macros the new ext functions to preserve backwards
compatibility
- add a new parameter to the ext functions, which are the
buffer->attrs
* split into separate patches the removal [from each driver] of
iio_buffer_set_attrs() and the switch to a
{devm_}iio_triggered_buffer_setup_ext variant
* add patch to remove iio_buffer_set_attrs() from DMAEngine IIO buffer
* remove the iio_buffer_set_attrs() helper in a final/separate patch
* add 'at91-sama5d2_adc: merge buffer & trigger' patch in this series,
so that the removal of iio_buffer_set_attrs() is easier to view
