* rtc: convert drivers/rtc/* to use module_platform_driver()Axel Lin2012-01-101-12/+1
| | | | | | | | | | | | | | | | | | | | | This patch converts the drivers in drivers/rtc/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.

* RTC: Clean out UIE icotl implementationsJohn Stultz2011-03-091-27/+0
| | | | | | | | | | | | | | | With the generic RTC rework, the UIE mode irqs are handled in the generic layer, and only hardware specific ioctls get passed down to the rtc driver layer. So this patch removes the UIE mode ioctl handling in the rtc driver layer, which never get used.

* RTC: Convert rtc drivers to use the alarm_irq_enable methodJohn Stultz2011-02-031-9/+12
| | | | | | | | | | | | | | | | | | | Some rtc drivers use the ioctl method instead of the alarm_irq_enable method for enabling alarm interupts. With the new virtualized RTC rework, its important for drivers to use the alarm_irq_enable instead. This patch converts the drivers that use the AIE ioctl method to use the alarm_irq_enable method. Other ioctl cmds are left untouched. I have not been able to test or even compile most of these drivers. Any help to make sure this change is correct would be appreciated!

* rtc-bfin: fix state restoration when resumingMike Frysinger2010-09-091-2/+11
| | | | | | | | | | | | | | | | | | | | | | | Much (but not all) of the RTC state is kept in the RTC peripheral which has its own power domain. Periodically (1 HZ), that state is synced from one power domain to the other (peripheral->core). When we are resuming, we need to wait for the sync to occur so that we don't get a mismatch of reading undefined state in the rest of the driver. Further, once the externally maintained bits have been synced back into the core, we then need to restore the bits maintained in the core. In our particular case, that is just the write completion interrupt bit. If we don't do any of this, working with the RTC causes ~5 second delays from time to time after waking up due to the write completion interrupt never firing.

| | | | | | | | | | | The int_clear helper takes a bitmask of interrupts to keep, not to disable.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+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.
