staging:iio: poll func allocation clean up.

2011-05-19T23:15:04+00:00

Add a function to neatly deal with allocation of poll functions.
Ultimately this allows us to more easily change the implementation.

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.

This case is extremely common, so let us only have the one

staging:iio: Add infrastructure for irq_chip based triggers

2011-05-19T23:14:48+00:00

V3: Get rid of separate interrupt pool. This is well handled
    by irq_get_descs and irq_free_descs.  Two functions I simply
    wasn't aware of previously.  Thus the allocation for a given
    trigger is now handled by core code rather than us reinventing
    the wheel.

V2: Stop silly name duplication.
    Move pool handling to industrialio-trigger as that is the only user.
    Changed over to using irq_modify_status rather than the arm
    specific set_irq_flags as per Thomas Gleixner's suggestion.
