2011-07-18staging:iio:accel:lis3l02dq: fix incorrect pointer passed to spi_set_drvdata.Jonathan Cameron
This mean all sorts of interesting results on driver removal. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-05-19staging:iio: implement an iio_info structure to take some of the constant ↵Jonathan Cameron
elements out of iio_dev. This was suggested by Arnd Bergmann, Other elements may well move in here in future, but it definitely makes sense for these. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-05-19staging:iio:accel:lis3l02dq make write_reg_8 take value not a pointer to value.Jonathan Cameron
Silliness that has been there a long time. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-05-19staging:iio: Rip out helper for software rings.Jonathan Cameron
It seemed like a good idea at the time, it wasn't. The code with this in place is larger and more complex for no real gain. Basically we've cleaned up the core around it so much that this no longer makes sense. Only really effects the lis3l02dq driver.

2011-05-19staging:iio:lis3l02dq remerge the two interrupt handlers.Jonathan Cameron
Does add a small burden to both handlers, but the gain is somewhat simpler code. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-05-19staging:iio:accel: lis3l02dq add writing for calibscale and calibbias.Jonathan Cameron
This was missed out in original chan_spec conversion. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-05-19staging:iio:accel:lis3l02dq move to threaded trigger handling.Jonathan Cameron
V2: Cleaned up handling of name string. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-05-19staging:iio:accel:lis3l02dq make threshold interrupt threaded.Jonathan Cameron
We have moved the timestamp acquisition into the bottom half. It may technically be less accurate but for this device I very much doubt anyone cares! Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-05-19staging:iio: Remove legacy event handling.Jonathan Cameron
This requires all drivers using the channel registration code and events to change in one go. V3: remove unwanted irq enable from event handler. V2: rebase related fixes to move to new IIO_CHAN macro. All trivial. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-05-19staging:iio: lis3l02dq - separate entirely interrupt handling for thesholds ↵Jonathan Cameron
from that for the datardy signal. This removes the one and only real user of the rather complex event list management. V3: More trivial rebase fixups. V2: Trivial rebase fixup. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-05-19staging:iio:lis3l02dq: General cleanupJonathan Cameron
As Arnd observed, things are clearner if we pass iio_dev into read and write fucntions. Now uses st for lis3l02dq_state everywhere. Other bits of trivial tidying. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-05-19staging:iio:lis3l02dq - move to new channel_spec approach.Jonathan Cameron
V3: Move to single IIO_CHAN macro. V2: Update to two part read_raw value. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-04-25staging:iio: Add ability to allocate private data space to iio_allocate_deviceJonathan Cameron
Suggested by Arnd Bergmann. Note this will break ALL drivers that are out of mainline. The fix is trivial change of iio_allocate_device() -> iio_allocate_device(0) Sorry if this causes issues for any one! V2: Include new drivers in the update Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
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.
