rtc: rtc-sh: switch to using SIMPLE_DEV_PM_OPS

2013-04-30T01:28:32Z

Switch to using the SIMPLE_DEV_PM_OPS macro to declare the driver's pm_ops. It reduces code size. Also, CONFIG_PM_SLEEP is added to prevent build warning when CONFIG_PM_SLEEP is not selected. Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rtc: rtc-sh: use module_platform_driver_probe()

2013-04-30T01:28:24Z

Use module_platform_driver_probe() macro which makes the code smaller and simpler. Signed-off-by: Jingoo Han Acked-by: Paul Mundt Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/rtc: remove IRQF_DISABLED

2012-03-23T23:58:39Z

Since commit e58aa3d2d0cc ("genirq: run irq handlers with interrupts disabled") we run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled - see commit b738a50a2026 ("genirq: warn when handler enables interrupts"). So now this flag is a NOOP and can be removed.

RTC: Clean out UIE icotl implementations

2011-03-09T19:24:54Z

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: Cleanup rtc_class_ops->irq_set_freq()

2011-03-09T19:23:35Z

With the generic rtc code now emulating PIE mode irqs via an hrtimer, no one calls the rtc_class_ops->irq_set_freq call. This patch removes the hook and deletes the driver functions if no one else calls them.

RTC: Cleanup rtc_class_ops->irq_set_state

2011-03-09T19:23:34Z

With PIE mode interrupts now emulated in generic code via an hrtimer, no one calls rtc_class_ops->irq_set_state(), so this patch removes it along with driver implementations.

RTC: Convert rtc drivers to use the alarm_irq_enable method

2011-02-03T21:02:35Z

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: rtc-sh - fix a memory leak

2010-11-08T06:08:42Z

request_mem_region() will call kzalloc to allocate memory for struct resource. release_resource() unregisters the resource but does not free the allocated memory, thus use release_mem_region() instead to fix the memory leak. Signed-off-by: Axel Lin Signed-off-by: Paul Mundt

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.
