The bios may clear the rtc control register when resuming the system. Since the cmos interrupt handler may now be run before the rtc_cmos is resumed, this can cause the interrupt handler to ignore an alarm since the alarm bit is not set in the rtc control register. To work around this, check if the rtc_cmos is suspended and use the stored value for the rtc control register. Signed-off-by:

Currently, the RTC IRQ is never wakeup-enabled so is not capable of bringing the system out of suspend. On OMAP platforms, we have gotten by without this because the TWL RTC is on an I2C-connected chip which is capable of waking up the OMAP via the IO ring when the OMAP is in low-power states. However, if the OMAP suspends without hitting the low-power states (and the IO ring is not enabled), RTC wakeups will not work because the IRQ is not wakeup enabled. To fix, ensure the RTC IRQ is wakeup enabled whenever the RTC alarm is set. Signed-off-by:

Use the wrapper functions for getting and setting the driver data using platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev, so we can directly pass a struct platform_device.

This chip has a control register and can prevent altering saved clock. Without this patch we could have: (arm)root@pac14:~# date Tue May 21 03:08:27 MSK 2013 (arm)root@pac14:~# /etc/init.d/hwclock.sh show Tue May 21 11:13:58 2013 -0.067322 seconds (arm)root@pac14:~# /etc/init.d/hwclock.sh stop [info] Saving the system clock. [info] Hardware Clock updated to Tue May 21 03:09:01 MSK 2013. (arm)root@pac14:~# /etc/init.d/hwclock.sh show Tue May 21 11:14:15 2013 -0.624272 seconds The patch enables write access to rtc before the driver tries to write time and re-disables when time data is written.

Android expects the RTC to have second resolution. On ab8540 cut2 RTC block has a new register which allows setting seconds for wakeup alarms. Existing registers (minutes hi, mid and low) have seen their offsets changed. Here is the new mapping: * AlarmSec (A) 0x22 * AlarmMinLow (M) from 0x8 to 0x23 * AlarmMinMid (M) from 0x9 to 0x24 * AlarmMinHigh (M) from 0xA to 0x25 Signed-off-by:
