2012-03-05drivers/rtc/rtc-r9701.c: fix crash in r9701_remove()Anatolij Gustschin1-7/+7
If probing the RTC didn't succeed due to failed RTC register access, the RTC device will be unregistered. Then, when removing the module r9701_remove() causes a kernel crash while trying to unregister a not registered RTC device. Fix this by doing RTC register access test before RTC device registration.

2012-01-26rtc: Disable the alarm in the hardware (v2)Rabin Vincent1-2/+13
Currently, the RTC code does not disable the alarm in the hardware. This means that after a sequence such as the one below (the files are in the RTC sysfs), the box will boot up after 2 minutes even though we've asked for the alarm to be turned off. # echo $((`cat since_epoch`)+120) > wakealarm # echo 0 > wakealarm # poweroff Fix this by disabling the alarm when there are no timers to run. The original version of this patch was reverted. This version disables the irq directly instead of setting a disabled timer in the future.

2012-01-26rtc: Expire alarms after the time is set. (v2)NeilBrown1-0/+4
If the alarm time programming in the rtc is ever in the past, it won't fire, and any other alarm will be queued after it so they won't fire either. So any time that the alarm might be in the past, we need to trigger the irq handler to ensure the old alarm is cleared and the timer queue is fully in the future. This is done whenever the RTC clock is set. This is the second revision of this patch, which was earlier reverted. This version avoids the initialization problem, which is handled by a different patch.

2012-01-26rtc: Avoid setting alarm to a time in the pastJohn Stultz1-1/+10
In some cases at boot up, the RTC alarm may be set in the past, but still have the enabled flag on. This was causing problems, because we would then enqueue the alarm into the timerqueue, but it would never fire. This would clog up the timerqueue and keep other alarms from working. The fix is to check the alarm against the current rtc time at boot and avoid enqueueing the alarm if it is in the past.

2012-01-19Revert "RTC: sa1100: remove redundant code of setting alarm"Russell King1-12/+41
This reverts commit 42874759d7494648e42e6e0465fc9c4f3752bba4. This wasn't tested as a stand-alone patch, and it has build errors without the following patches applied: drivers/rtc/rtc-sa1100.c: In function 'sa1100_rtc_set_alarm': drivers/rtc/rtc-sa1100.c:208: error: 'now' undeclared (first use in this function) drivers/rtc/rtc-sa1100.c:208: error: (Each undeclared identifier is reported only once drivers/rtc/rtc-sa1100.c:208: error: for each function it appears in.) drivers/rtc/rtc-sa1100.c:210: error: incompatible type for argument 3 of 'rtc_next_alarm_time' drivers/rtc/rtc-sa1100.c:211: error: 'time' undeclared (first use in this function) So it too gets reverted to bring us back to a working point.

This reverts commit 7cea00657dd4daef66ad95e976d5d67ed94cb97e.

2012-01-10drivers/rtc/interface.c: fix alarm rollover when day or month is out-of-rangeBen Hutchings1-2/+2
Commit f44f7f96a20a ("RTC: Initialize kernel state from RTC") introduced a potential infinite loop. If an alarm time contains a wildcard month and an invalid day (> 31), or a wildcard year and an invalid month (>= 12), the loop searching for the next matching date will never terminate. Treat the invalid values as wildcards.

This moves all the header files related to the abx500 family into a common include directory below mfd. From now on we place any subchip header in that directory. Headers previously in e.g. <linux/mfd/ab8500/gpio.h> get prefixed and are now e.g. <linux/mfd/abx500/ab8500-gpio.h>. The top-level abstract interface remains in <linux/mfd/abx500.h>.

2012-01-04Revert "rtc: Expire alarms after the time is set."Linus Torvalds1-6/+0
This reverts commit 93b2ec0128c431148b216b8f7337c1a52131ef03. The call to "schedule_work()" in rtc_initialize_alarm() happens too early, and can cause oopses at bootup Neil Brown explains why we do it: "If you set an alarm in the future, then shutdown and boot again after that time, then you will end up with a timer_queue node which is in the past. When this happens the queue gets stuck. That entry-in-the-past won't get removed until and interrupt happens and an interrupt won't happen because the RTC only triggers an interrupt when the alarm is "now". So you'll find that e.g. "hwclock" will always tell you that 'select' timed out. So we force the interrupt work to happen at the start just in case." and has a patch that convert it to do things in-process rather than with the worker thread, but right now it's too late to play around with this, so we just revert the patch that caused problems for now.

2012-01-03Revert "rtc: Disable the alarm in the hardware"Linus Torvalds1-34/+10
This reverts commit c0afabd3d553c521e003779c127143ffde55a16f. It causes failures on Toshiba laptops - instead of disabling the alarm, it actually seems to enable it on the affected laptops, resulting in (for example) the laptop powering on automatically five minutes after shutdown. There's a patch for it that appears to work for at least some people, but it's too late to play around with this, so revert for now and try again in the next merge window.
