2012-04-25IIO: Move core headers to include/linux/iioJonathan Cameron
Step 1 in moving the IIO core out of staging. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-04-24staging:iio: Add caching of scan_timestamp to the core as well as buffers.Jonathan Cameron
This will be needed when multiple buffer support is added. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Acked-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-02-09staging:iio: Setup buffer access functions when allocating the bufferLars-Peter Clausen
Setup the buffer access functions in the buffer allocate function. There is no need to let each driver handle this on its own. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2011-12-08staging:iio:buffer remove unused owner field from struct iio_bufferJonathan Cameron
Legacy of having multiple chrdevs that never got cleaned up. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Acked-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-12-08staging:iio: scrap scan_count and ensure all drivers use active_scan_maskJonathan Cameron
Obviously drivers should only use this for pushing to buffers. They need buffer->scan_mask for pulling from them post demux. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Acked-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-12-08staging:iio:buffer move setup ops from buffer instance to iio_devJonathan Cameron
These callbacks should not be buffer instance specific. Hence move them out of the buffer. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Acked-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-12-08staging:iio:buffer drop bpe field.Jonathan Cameron
Has no remaining users. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Acked-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-10-31staging: Add export.h for THIS_MODULE/EXPORT_SYMBOL to drivers/staging users.Paul Gortmaker
Lots of drivers have in the past expected the presence of basic things like THIS_MODULE and EXPORT_SYMBOL. With the header cleanup, they wont have these. Call out the include explicitly. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-09-27staging:iio: replacing term ring with buffer in the IIO core.Jonathan Cameron
They aren't always ring buffers, so just use buffer for all naming. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-09-27staging:iio: tree wide IIO_RING_TRIGGERED -> IIO_BUFFER_TRIGGEREDJonathan Cameron
also, IIO_RING_HARDWARE_BUFFER -> IIO_BUFFER_HARDWARE These aren't always rings so the naming should not imply that. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-09-27staging:iio: treewide rename iio_triggered_ring_* to iio_triggered_buffer_*Jonathan Cameron
Not always a ring so naming is missleading. Also, kfifo_buf is probably first buffer to take out of staging and it definitely isn't a ring. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-09-06staging:iio:various move default scan mask setting after ring register or removeJonathan Cameron
The scan mask will be dynamically assigned in register, so don't use it before that. In adis16260 I've moved it as I know this driver has userspace code. Same for sca3000 where it is cost free due to hardware buffer. Can do that for the others, but in theory userspace code should always have been checking these and setting them appropriately anyway! V2: Clear default mask out of adis16400 as reported by Michael Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Reported-by: Michael Hennerich <michael.hennerich@analog.com> Acked-by: Michael Hennerich <Michael.Hennerich@analog.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-05-19staging:iio: poll func allocation clean up.Jonathan Cameron
Add a function to neatly deal with allocation of poll functions. Ultimately this allows us to more easily change the implementation. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-05-19staging:iio: rationalization of different buffer implementation hooks.Jonathan Cameron
1) move a generic helper function out of ring_sw. It applies to other buffers as well. 2) Get rid of a lot of left over function definitions. 3) Move all the access functions into static structures. 4) Introduce and use a static structure for the setup functions, preenable etc. Some driver conversions thanks to Michael Hennerich (pulled out of patches that would otherwise sit after this).

2011-05-19staging:iio:accel:adis16209 move to chan_spec based setup.Jonathan Cameron
For clean drivers its easier to convert to chan_spec based registration than to work around the scan_el attributes going away. Some minor cleanups done whilst here. Untested. V2: IIO_CHAN macro used.

2010-06-18Staging: iio: pull in slab.h for kmalloc funcsMike Frysinger
These drivers use kzalloc() but don't include slab.h. They currently build though because the spi.h header will pull in slab.h for us. But rather than rely on that behavior forever, include slab.h explicitly.
