* ARM: at91: fix new build errorsArnd Bergmann2012-07-041-0/+1
| | | | | | | | | | | | | | | | MULTI_IRQ_HANDLER and SPARSE_IRQ are now required everywhere because mach/irqs.h and mach/entry-macros.S are gone but the symbols are only selected for AT91SAM9, not for the NOMMU parts. A few files now need to include linux/io.h directly, which used to be included through other headers that have changed. The new at91_aic_irq_priorities variable is only used with CONFIG_OF enabled and should not be visible otherwise.

* RTC: Clean out UIE icotl implementationsJohn Stultz2011-03-091-28/+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 Stultz2011-02-031-7/+13
| | | | | | | | | | | | | | | | | | | 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-at91rm9200: avoid spurious irqsDavid Brownell2008-07-241-10/+6
| | | | | | | | | | | | | | | | | | | | This fixes kernel http://bugzilla.kernel.org/show_bug.cgi?id=11112 (bogus RTC update IRQs reported) for rtc-at91rm9200 by scrubbing old IRQ status before enabling IRQs. It also removes nonfunctional periodic IRQ support from this driver; only update IRQs are reported, or provided by the hardware. I suspect some other RTCs probably have versions of #11112; it's easy to overlook, since most non-RTC drivers don't care about spurious IRQs: they're not reported to userspace.

* [RTC] remove unused asm/rtc.h includes from ARM RTC driversRussell King2008-05-221-2/+0
| | | | | | | | | | | On ARM, asm/rtc.h only contains definitions for the predecessor to the RTC class support. RTC class drivers should not be including this include.

| | | | | | | | | | | | | asm/mach/time.h is the ARM header file for setting up kernel ticker timekeeping (be that the old jiffy interrupt or the new clocksource.)

* rtc: suspend()/resume() restores system clockDavid Brownell2007-05-081-30/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | RTC class suspend/resume support, re-initializing the system clock on resume from the clock used to initialize it at boot time. - The reinit-on-resume is hooked to the existing RTC_HCTOSYS config option, on the grounds that a clock good enough for init must also be good enough for re-init. - Inlining a version of the code used by ARM, to save and restore the delta between a selected RTC and the current system wall-clock time. - Removes calls to that ARM code from AT91, OMAP1, and S3C RTCs. This means that systems using those RTCs across suspend/resume will likely want to change their kernel configs to enable RTC_HCTOSYS. If HCTOSYS isn't using a second RTC (with battery?), this changes the system's initial date from Jan 1970 to the epoch this hardware uses: 1998 for AT91, 2000 for OMAP1 (assuming no split power mode), etc. This goes on top of the patch series removing "struct class_device" usage from the RTC framework. That's all needed for class suspend()/resume().

* [PATCH] at91_rtc updatesDavid Brownell2007-02-211-6/+13
| | | | | | | | | | | | | | | | | | | | | | | Various bug fixes to the at91rm9200 RTC: - alarm: setalarm() should pay attention to the "enabled" flag - init: cleaner handling of the wakeup flags, which cpu init should really have set up. Doing it here is just a workaround. - linkage: since the at91_rtc driver probe() routine is in the init section, it should use platform_driver_probe() instead of leaving that pointer around in the driver struct after init section removal. - linkage: likewise, remove() belongs in the exit section. Among other things, the init and alarm changes ensure that this driver handles the new sysfs "wakealarm" attribute properly.

* [PATCH] rtc framewok: rtc_wkalrm.enabled reporting updatesDavid Brownell2006-12-131-2/+3
| | | | | | | | | | | | | | | | Fix a glitch in the procfs dumping of whether the alarm IRQ is enabled: use the traditional name (from drivers/char/rtc.c and many other places) of "alarm_IRQ", not "alrm_wakeup" (which didn't even match the efirtc code, which originated that reporting API). Also, update a few of the RTC drivers to stop providing that duplicate status, and/or to expose it properly when reporting the alarm state.

* [PATCH] AT91RM9200 RTCAndrew Victor2006-12-101-0/+429
The new Atmel AT91SAM9261 and AT91SAM9260 processors do not have the internal RTC peripheral. This RTC driver is therefore AT91RM9200-specific. This patch renames rtc-at91.c to rtc-at91rm9200.c, and changes the name of the configuration option.
