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.

2012-03-03ARM: S3C24XX: change the ARCH_S3C2410 to ARCH_S3C24XXKukjin Kim1-1/+1
This patch changes the ARCH name to "ARCH_S3C24XX" for Samsung S3C2410, S3C2412, S3C2413, S3C2416, S3C2440, S3C2442, S3C2443, and S3C2450 SoCs so that we can merge the mach-xxx directories and plat-s3c24xx dir. to just one mach-s3c24xx for them. I think this should be sent to upstream via samsung tree because this touches many samsung stuff.

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.

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.

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.

2012-01-10rtc-puv3: solve section mismatch in rtc-puv3.cGuan Xuetao1-2/+2
The patch renames puv3_rtcdrv to puv3_rtc_driver, so that modpost will know that this is simply a list of pointers to driver functions, in which case the section mismatch is OK.

2012-01-09mfd: Unify abx500 headers in mfd/abx500Linus Walleij1-1/+1
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>.
