2015-03-04rtc: at91rm9200: rework wakeup and interrupt handlingBoris BREZILLON1-14/+48
The IRQ line used by the RTC device is usually shared with the system timer (PIT) on at91 platforms. Since timers are registering their handlers with IRQF_NO_SUSPEND, we should expect being called in suspended state, and properly wake the system up when this is the case. Set IRQF_COND_SUSPEND flag when registering the IRQ handler to inform irq core that it can safely be called while the system is suspended.

2014-06-06rtc: rtc-at91rm9200: fix infinite wait for ACKUPD irqBoris BREZILLON1-2/+14
The rtc user must wait at least 1 sec between each time/calandar update (see atmel's datasheet chapter "Updating Time/Calendar"). Use the 1Hz interrupt to update the at91_rtc_upd_rdy flag and wait for the at91_rtc_wait_upd_rdy event if the rtc is not ready. This patch fixes a deadlock in an uninterruptible wait when the RTC is updated more than once every second. AFAICT the bug is here from the beginning, but I think we should at least backport this fix to 3.10 and the following longterm and stable releases.

2013-11-21ARM: drivers/rtc/rtc-at91rm9200.c: disable interrupts at shutdownJohan Hovold1-0/+9
Make sure RTC-interrupts are disabled at shutdown. As the RTC is generally powered by backup power (VDDBU), its interrupts are not disabled on wake-up, user, watchdog or software reset. This could cause troubles on other systems (e.g. older kernels) if an interrupt occurs before a handler has been installed at next boot. Let us be well-behaved and disable them on clean shutdowns at least (as do the RTT-based rtc-at91sam9 driver).

The added overhead is not an issue for the non-broken SoCs due to the relatively infrequent interrupt-mask updates.

2013-06-12rtc-at91rm9200: add match-table compile guardJohan Hovold1-0/+2
The members of Atmel's at91sam9x5 family (9x5) have a broken RTC interrupt mask register (AT91_RTC_IMR). It does not reflect enabled interrupts but instead always returns zero. The kernel's rtc-at91rm9200 driver handles the RTC for the 9x5 family. Currently when the date/time is set, an interrupt is generated and this driver neglects to handle the interrupt. The kernel complains about the un-handled interrupt and disables it henceforth. This not only breaks the RTC function, but since that interrupt is shared (Atmel's SYS interrupt) then other things break as well (e.g. the debug port no longer accepts characters). Tested on the at91sam9g25. Bug confirmed by Atmel. This patch (of 5): Add missing match-table compile guard.

This reverts commit 0ef1594c017521ea89278e80fe3f80dafb17abde. This patch introduced a few races which cannot be easily fixed with a small follow-up patch.

2013-03-22drivers/rtc/rtc-at91rm9200.c: use a variable for storing IMRNicolas Ferre1-19/+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.

2007-05-08rtc: suspend()/resume() restores system clockDavid Brownell1-30/+0
RTC class suspend/resume support, re-initializing the system clock on resume from the clock used to initialize it at boot time. - The reinit-on-resume is hooked to the existing RTC_HCTOSYS config option, on the grounds that a clock good enough for init must also be good enough for re-init. - Inlining a version of the code used by ARM, to save and restore the delta between a selected RTC and the current system wall-clock time. - Removes calls to that ARM code from AT91, OMAP1, and S3C RTCs. This means that systems using those RTCs across suspend/resume will likely want to change their kernel configs to enable RTC_HCTOSYS. If HCTOSYS isn't using a second RTC (with battery?), this changes the system's initial date from Jan 1970 to the epoch this hardware uses: 1998 for AT91, 2000 for OMAP1 (assuming no split power mode), etc. This goes on top of the patch series removing "struct class_device" usage from the RTC framework. That's all needed for class suspend()/resume().

Various bug fixes to the at91rm9200 RTC: - alarm: setalarm() should pay attention to the "enabled" flag - init: cleaner handling of the wakeup flags, which cpu init should really have set up. Doing it here is just a workaround. - linkage: since the at91_rtc driver probe() routine is in the init section, it should use platform_driver_probe() instead of leaving that pointer around in the driver struct after init section removal. - linkage: likewise, remove() belongs in the exit section.
