* drivers/rtc/: use bcd2bin/bin2bcdAdrian Bunk2008-10-201-21/+21
| | | | | | | | | | | Change drivers/rtc/ to use the new bcd2bin/bin2bcd functions instead of the obsolete BCD_TO_BIN/BIN_TO_BCD/BCD2BIN/BIN2BCD macros.

* 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. Build tested on at91sam9rl and s3c2410 configurations. Acked-by: Alessandro Zummo <a.zummo@towertech.it> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [RTC] remove references to asm/mach/time.hRussell King2008-05-221-2/+0
| | | | | | | | | | | | | 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 drivers have no business using this header file, and in fact do not require it. Build tested on at91sam9rl, omap and s3c2410 configurations.

* rtc: fix platform driver hotplug/coldplugKay Sievers2008-04-111-0/+1
| | | | | | | | | | | | | | Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable RTC platform drivers, to re-enable module auto loading.

* 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().

* rtc: rtc interfaces don't use class_deviceDavid Brownell2007-05-081-1/+1
| | | | | | | | | | | | This patch removes class_device from the programming interface that the RTC framework exposes to the rest of the kernel. Now an rtc_device is passed, which is more type-safe and streamlines all the relevant code.

* [PATCH] at91_rtc updatesDavid Brownell2007-02-201-6/+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. We really don't want every RTC driver doing their own thing here...

* [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.
