* staging:iio:imu:adis16350 etc support into adis16400 driver.Jonathan Cameron2011-05-205-47/+260
| | | | | | | | | | | | | | | Next patch will remove the current adis16350 driver. These should have been merged a long time ago, but there we are. V3: rebase fixup + add missing extend_name for supply on adis16350 V2: Move to single IIO_CHAN macro + use the new extend_name to make the naming of the temperature sensors contain x, y, z rather than messing with modifiers. This a very weird case and I don't want temperature to use axial modifiers. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Fix from Michael Hennerich incorporated to use iio_ring_buffer_register_ex instead of iio_ring_buffer_register and thus actually make it work.

* staging:iio: Add infrastructure for irq_chip based triggersJonathan Cameron2011-05-203-36/+203
| | | | | | | | | | | | | | | | 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.

* staging:iio: Remove legacy event handling.Jonathan Cameron2011-05-208-600/+85Star
| | | | | | | | | | | This requires all drivers using the channel registration code and events to change in one go. V3: remove unwanted irq enable from event handler.

* staging:iio:adc:adt7410 move to current event handlingJonathan Cameron2011-05-201-90/+61Star
| | | | | | | | | This device actually has a pair of interrupts. The code basically ignores that and feeds them both to the same handlers. I'm not sure if that is the right thing to do, but the updated code should do exactly the same. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | | | | | as gpio requirement. Another driver with some very 'non standard' magic event codes. Again I've left it be for now and merely moved it to the new api. There is no reason why the irq in this driver ever had to be a gpio. Scrap that test and clean out unecessary headers.

| | | | | | | | | I'm not sure what the event is and am very much against the dodgy hack to give it a code. However for now, lets just stop it using the deprecated core handling so we can move on. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | | | | | from buffer Fairly substantial rewrite as the code had bitrotted. A rethink is needed for how to handle variable types in the new chan_spec world.

| | | | | | | | | | | | | | Whilst it is possible to output events to say buffers have passed a particular level there are no obvious reasons to actually do so. The upshot of this patch is that buffers will only ever have one threshold turned on at a time. For now sca3000 has it's ring buffer effectively disabled. Fixed later in series.
