rtc-cmos: fix suspend/resume

2011-03-31T18:57:48+00:00

commit 2fb08e6ca9f00d1aedb3964983e9c8f84b36b807 upstream. rtc-cmos was setting suspend/resume hooks at the device_driver level. However, the platform bus code (drivers/base/platform.c) only looks for resume hooks at the dev_pm_ops level, or within the platform_driver. Switch rtc_cmos to use dev_pm_ops so that suspend/resume code is executed again. Paul said: : The user visible symptom in our (XO laptop) case was that rtcwake would : fail to wake the laptop. The RTC alarm would expire, but the wakeup : wasn't unmasked. : : As for severity, the impact may have been reduced because if I recall : correctly, the bug only affected platforms with CONFIG_PNP disabled.

rtc: rs5c372: fix buffer size

2011-02-06T19:03:48+00:00

commit 118364948fad7b6c0469ef2d3ddaee447d7a0b5f upstream. Match the buffer size to the amount of initialized values. Before, it was one too big and thus destroyed the neighbouring register causing the clock to run at false speeds.

rtc: s3c: balance state changes of wakeup flag

2010-09-27T00:18:27+00:00

commit f501ed524b26ba1b739b7f7feb0a0e1496878769 upstream. This change resolves a problem about unbalanced calls of enable_irq_wakeup() and disable_irq_wakeup() for alarm interrupt.

drivers/rtc/rtc-rx8581.c: fix setdatetime

2010-07-27T21:32:06+00:00

Fix the logic while writing new date/time to the chip. The driver incorrectly wrote back register values to different registers and even with wrong mask. The patch adds clearing of the VLF register, which should be cleared if all date/time values are set.

rtc: fix ds1388 time corruption

2010-06-29T22:29:31+00:00

The ds1307 driver misreads the ds1388 registers when checking for 12 or 24 hour mode. Instead of checking the hour register it reads the minute register. Therefore the driver thinks minutes >= 40 has the 12HR bit set and resets the minute register by zeroing the high bits. This results in minutes are reset to 0-9, jumping back in time 40 or 50 minutes. The time jump is also written back to the RTC.
