2012-01-10drivers/rtc/interface.c: fix alarm rollover when day or month is out-of-rangeBen Hutchings
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.

2012-01-10drivers/rtc/: remove redundant spi driver bus initializationLars-Peter Clausen
In ancient times it was necessary to manually initialize the bus field of an spi_driver to spi_bus_type. These days this is done in spi_driver_register(), so we can drop the manual assignment.

Use the hrtimer-based usleep_range() and allow for some slack in the non-critical path so we have more control of what is happening here.

2012-01-04Revert "rtc: Expire alarms after the time is set."Linus Torvalds
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.

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.

2011-12-13rtc: m41t80: Workaround broken alarm functionalityJohn Stultz
The m41t80 driver can read and set the alarm, but it doesn't seem to have a functional alarm irq. This causes failures when the generic core sees alarm functions, but then cannot use them properly for things like UIE mode. Disabling the alarm functions allows proper error reporting, and possible fallback to emulated modes. Once someone fixes the alarm irq functionality, this can be restored.

2011-12-13rtc: Expire alarms after the time is set.NeilBrown
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 can happen: - when we first initialise the alarm - when we set the time in the rtc. so follow both of these by scheduling the timer work function.

2011-11-22rtc: Fix some bugs that allowed accumulating time drift in suspend/resumeArve Hjønnevåg
The current code checks if abs(delta_delta.tv_sec) is greater or equal to two before it discards the old delta value, but this can trigger at close to -1 seconds since -1.000000001 seconds is stored as tv_sec -2 and tv_nsec 999999999 in a normalized timespec. rtc_resume had an early return check if the rtc value had not changed since rtc_suspend. This effectivly stops time for the duration of the short sleep. Check if sleep_time is positive after all the adjustments have been applied instead since this allows the old_system adjustment in rtc_suspend to have an effect even for short sleep cycles.

2011-11-22rtc: Disable the alarm in the hardwareRabin Vincent
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.

2011-11-11vrtc: change its year offset from 1960 to 1972Feng Tang
Real world year equals the value in vrtc YEAR register plus an offset. We used 1960 as the offset to make leap year consistent, but for a device's first use, its YEAR register is 0 and the system year will be parsed as 1960 which is not a valid UNIX time and will cause many applications to fail mysteriously. So we use 1972 instead to fix this issue. Updated patch which adds a sanity check suggested by Mathias This isn't a change in behaviour for systems, because 1972 is the one we actually use. It's the old version in upstream which is out of sync with all devices.
