2011-12-08staging:iio:adc:max1363 stop reading from buffer for sysfs accessJonathan Cameron1-36/+0

2011-11-26staging:iio: header reorganizationJonathan Cameron1-1/+1
Issue brought up by Lars-Peter Clausen. This is a varient of what he suggested. io/iio.h for driver stuff (has to include types.h) Sub files for the bits drivers may or may not use iio/sysfs.h iio/buffer.h (contents of current buffer_generic.h) (obviously anything offering events will need events.h as well) iio/types.h for the enums that matter to both iio_chan_type, iio_modifier iio/events.h for the event code stuff IIO_EVENT_CODE and friends. + everything in chrdev.h So this is the stuff that userspace cares about. Also include iio_event_type, iio_event_direction Thus iio drivers include iio.h + as required events.h sysfs.h buffer.h in kernel users (once that interface is merged) will need inkern.h which will pull in types.h Userspace will need just events.h (which pulls in types.h) to get everything they need to know about. Buffer userspace access doesn't currently need any core defines. All information about the data format is passed through sysfs.

2011-09-26staging:iio: replacing term ring with buffer in the IIO core.Jonathan Cameron1-10/+10
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>

2011-09-26staging:iio: tree wide IIO_RING_TRIGGERED -> IIO_BUFFER_TRIGGEREDJonathan Cameron1-1/+1
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>
2011-09-26staging:iio: treewide rename iio_triggered_ring_* to iio_triggered_buffer_*Jonathan Cameron1-2/+2
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: Switch the channel masks to bitmaps so as to allow for more ↵Jonathan Cameron1-11/+11
channels. This is as light as possible on changes to current drivers. Some drivers make assumptions that their masks fit in a single long. Given they were previously working this is clearly valid if not tidy. The max1363 is an example where there should be no such assumptions.

2011-05-19staging:iio: rationalization of different buffer implementation hooks.Jonathan Cameron1-12/+14
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).

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo1-0/+1
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
