staging:iio: iio_trigger contains defunct owner field. Remove it.

2011-12-16T18:56:26+00:00

This field moved into the trigger_ops structure a while back, but somehow
never quite got cleared up.  This clears the last few drivers to set it
(nothing uses it) and gets rid of it entirely.

staging:iio:trigger:sysfs trigger: Add a release function to avoid warning on module removal.

2011-08-24T21:23:41+00:00

The device is static and should never actually be deleted. The release
is just to avoid a warning from the kernel.

staging:iio:triggers introduce iio_trigger_ops to take const bits out of iio_trig_structure.

2011-08-23T20:31:06+00:00

Right now this results in increased code, but I still think it is worth doing to avoid
replication across instances of drivers etc and move as much stuff as possible to constant.
Ops structure is optional for the occasional driver that uses none of it (currently
only the ad7793).

staging:iio:trigger handle name attr in core, remove old alloc and register any control_attrs via struct device

2011-05-19T23:15:02+00:00

As the majority of triggers don't actually have any other control_attrs lets use the fact
that struct device has a groups element when we do need to have these attributes registered.
A vargs function is used to cut down on lots of building strings in every single driver
just in order to pass them into the allocate.

Also iio_allocate_trigger_named -> iio_allocate_trigger as there is no
unamed version any more, so that is now just confusing.

Blackfin tested and fixed by Michael Hennerich.

staging:iio:trigger sysfs userspace trigger rework.

2011-05-19T23:15:00+00:00

Awaiting comments on using the nested_irq_trick so that may change.
Moves away from platform device to sysfs controlled creation and
removal of these triggers.

Fix double free of name on trigger allocation failure thanks
to Michael Hennerich.

staging: IIO: trigger: New Blackfin specific trigger driver iio-trig-bfin-timer

2011-02-23T22:40:04+00:00

This driver allows any Blackfin system timer to be used as IIO trigger.
It supports trigger rates from 0 to 100kHz in Hz resolution.

Changes since V1:
IIO: trigger: Apply review feedback

Add comment explaining Blackfin hardware timer configurations
Fix frequency_store, don't return -EINVAL for frequency set to 0

Staging: IIO: TRIGGER: New sysfs based trigger

2011-02-09T22:56:42+00:00

This patch adds a new trigger that can be invoked by writing
the sysfs file: trigger_now. This approach can be valuable during
automated testing or in situations, where other trigger methods
are not applicable. For example no RTC or spare GPIOs.
Last but not least we can allow user space applications to produce triggers.

IIO: TRIGGER: Apply review feedback by Greg Kroah-Hartman

Changes since v1:

Add sysfs documentation.
Change license notice.
Add module alias.
Add more Kconfig help text
