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:trigger handle name attr in core, remove old alloc and register ↵Jonathan Cameron
any control_attrs via struct device 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.

2011-05-19staging:iio:gyro:adis16260 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. V3: rebase fixup and make attribute_group static. V2: IIO_CHAN macro updates. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

If the part get's probed twice without hard reset in between, the power on default register read-back can't be met. This shouldn't cause the second probe to fail. So warn but don't exit.

2011-02-28staging:iio:gyro: adis16060 cleanup, move to abi and bug fixes.Jonathan Cameron
Moved to standard sysfs naming and got rid of direct register writing from userspace. The rx and tx buffers are never used together so just have one and avoid the need to malloc it by using putting it in the state structure and using the ____cacheline_aligned trick. A number of obvious bugs also fixed and correction of register address defines in header which has now been squashed into the driver. I don't have one of these so can't test. This is done off datasheet. Note that the driver had parts that definitely wouldn't work before this patch. Now it 'might' assuming I haven't messed up too badly. I've left fixing the fact that you can only have one of these on a given machine for another day.
