* Revert "drivers/rtc/rtc-at91rm9200.c: use a variable for storing IMR"Johan Hovold2013-04-052-31/+20
| | | | | | | | | | | | | | | | | This reverts commit 0ef1594c017521ea89278e80fe3f80dafb17abde. This patch introduced a few races which cannot be easily fixed with a small follow-up patch. Furthermore, the SoC with the broken hardware register, which this patch intended to add support for, can only be used with device trees, which this driver currently does not support.

* drivers/rtc/rtc-at91rm9200.c: use a variable for storing IMRNicolas Ferre2013-03-222-20/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some revisions of AT91 SoCs, the RTC IMR register is not working. Instead of elaborating a workaround for that specific SoC or IP version, we simply use a software variable to store the Interrupt Mask Register and modify it for each enabling/disabling of an interrupt. The overhead of this is negligible anyway. The interrupt mask register (IMR) for the RTC is broken on the AT91SAM9x5 sub-family of SoCs (good overview of the members here: http://www.eewiki.net/display/linuxonarm/AT91SAM9x5 ). The "user visible effect" is the RTC doesn't work. That sub-family is less than two years old and only has devicetree (DT) support and came online circa lk 3.7 . The dust is yet to settle on the DT stuff at least for AT91 SoCs (translation: lots of stuff is still broken, so much that it is hard to know where to start). The fix in the patch is pretty simple: just shadow the silicon IMR register with a variable in the driver. Some older SoCs (pre-DT) use the the rtc-at91rm9200 driver (e.g. obviously the AT91RM9200) and they should not be impacted by the change. There shouldn't be a large volume of interrupts associated with a RTC.

The enabling/disabling of interrupt happen in sequence of interrupt registration with framework. Therefore, in resume, the parent interrupt of this device enabled before the RTC irq interrupt enabled. If RTC is enabled for alarm wake and if system wake by alarm then there is interrupt pending for RTC. In resume, the parent interrupt get enabled before the rtc interrupt and hence ISR get served. In ISR, it founds that rtc interrupt is disabled and so it does not call the rtc isr handler and hence it misses the interrupt. Setting flag for early resume so that rtc interrupt get enabled before parent interrupt and so rtc interrupt get enabled when parent interrupt handler check for interrupt of device and call the rtc handler if it is there. This way it will not miss the interrupt.

| * | drivers/rtc/rtc-tps65910.c: remove unnecessary irq stat save and restoreLaxman Dewangan2013-02-211-19/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver stores the interrupt enable register before going to suspend and restore in resume. Also it enables alarm before going to suspend. The driver only write the Interrupt enable register for enabling ALARM and does not enable any other bits. So it is not require to save complete register and enable ALARM interrupt before suspend and restore in resume. Also ALARM interrupt already enable if alarm is enabled before going to suspend and hence it is not require to enable explictly in suspend. Removing such above code.
