2011-12-01T07:41:42Z

Commit 940ab88962bc1aff3273a8356d64577a6e386736 introduced a new macro to save some platform_driver boilerplate code. Use it. Signed-off-by: JJ Ding Signed-off-by: Dmitry Torokhov

doc: fix broken references

2011-09-27T16:08:04Z

There are numerous broken references to Documentation files (in other Documentation files, in comments, etc.). These broken references are caused by typo's in the references, and by renames or removals of the Documentation files. Some broken references are simply odd. Fix these broken references, sometimes by dropping the irrelevant text they were part of. Signed-off-by: Paul Bolle Signed-off-by: Jiri Kosina

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h

2010-03-30T13:02:32Z

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.

Input: rotary-encoder - set gpio direction for each requested gpio

2010-02-11T07:19:48Z

Even with the correct pin mux settings, you still need to explicitly set the gpio direction. Call gpio_direction_input() after each requested gpio. Signed-off-by: Andrew Clayton Signed-off-by: Mark Somerville Tested-by: H Hartley Sweeten Acked-by: Daniel Mack Signed-off-by: Dmitry Torokhov

Input: rotary_encoder - fix relative axis support

2009-10-06T05:00:01Z

When the rotart_encoder driver is used to report relative axis information the "steps" in the platform data could be missing since it's not relevant. Signed-off-by: H Hartley Sweeten Acked-by: Daniel Mack Signed-off-by: Dmitry Torokhov

Input: rotary_encoder - add support for REL_* axes

2009-04-18T03:37:21Z

The rotary encoder driver only supports returning input events for ABS_* axes, this adds support for REL_* axes. The relative axis input event is reported as -1 for each counter-clockwise step and +1 for each clockwise step. The ability to clamp the position of ABS_* axes between 0 and a maximum of "steps" has also been added. Signed-off-by: H Hartley Sweeten Signed-off-by: Daniel Mack Signed-off-by: Dmitry Torokhov

Input: generic driver for rotary encoders on GPIOs

2009-03-08T23:35:53Z

This patch adds a generic driver for rotary encoders connected to GPIO pins of a system. It relies on gpiolib and generic hardware irqs. The documentation that also comes with this patch explains the concept and how to use the driver. Signed-off-by: Daniel Mack Tested-by: H Hartley Sweeten Signed-off-by: Dmitry Torokhov
