iio: core-trigger: make iio_device_register_trigger_consumer() an int return

2021-03-11T20:47:02+00:00

Oddly enough the noop function is an int-return. This one seems to be void.
This change converts it to int, because we want to change how groups are
registered. With that change this function could error out with -ENOMEM.

iio: trigger: make stub functions static inline

2020-08-22T09:53:18+00:00

Make sure that the trigger function stubs are all static inline.
Otherwise we might see compiler warnings about declared but unused
functions.

iio: Move attach/detach of the poll func to the core

2020-06-20T16:34:44+00:00

All devices using a triggered buffer need to attach and detach the trigger
to the device in order to properly work. Instead of doing this in each and
every driver by hand move this into the core.

At this point in time, all drivers should have been resolved to
attach/detach the poll-function in the same order.

This patch removes all explicit calls of iio_triggered_buffer_postenable()
& iio_triggered_buffer_predisable() in all drivers, since the core handles
now the pollfunc attach/detach.

The more peculiar change is for the 'at91-sama5d2_adc' driver, since it's
not immediately obvious that removing the hooks doesn't break anything.
Eugen was able to test on at91-sama5d2-adc driver, sama5d2-xplained board.
All seems to be fine.

IIO: Move the core files to drivers/iio

2012-04-25T18:11:38+00:00

Take the core support + the kfifo buffer implentation out of
staging.  Whilst we are far from done in improving this subsystem
it is now at a stage where the userspae interfaces (provided by
the core) can be considered stable.

Drivers will follow over a longer time scale.
