Subject[PATCH v2 0/5] iio: Add output buffer support
Date
This patchset is based on the new multibuffer set.
It doesn't require the high-speed/mmap interface.
That will come later on a v2.

Changelog v1 -> v2:
* https://lore.kernel.org/linux-iio/20210212102021.47276-4-alexandru.ardelean@analog.com/T/#u
* removed DMA patches for now
* in patch 'iio: Add output buffer support'
- added /sys/bus/iio/devices/iio:deviceX/bufferY/direction attribute
- thinking about this, an update to the new buffer infrastructure is
required when adding ADDAC/MxFE/transceivers; right now there is no
problem, because we have only ADCs and DACs; but when we get
transceivers, a bufferY/ directory needs to filter in/out
scan_elements/ ; this only occured to me recently (it's one of those
things that pops up later in mind)
* added 'iio: Documentation: update definitions for bufferY and scan_elements'
- seems I forgot this on the original multibuffer patchset
* added 'iio: triggered-buffer: extend support to configure output buffers'
- basically output triggered buffer support
* added 'iio: dac: ad5686: Add PWM as a trigger source'
- this is a first user of this infrastructure
