| | | | | | | | | | | | | | | | | | | On some platforms (like AM33xx), a special register (RTC_IRQWAKEEN) is available to enable Alarm Wakeup feature. This register needs to be properly handled for the rtcwake to work properly. Platforms using such IP should set "ti,am3352-rtc" in rtc device dt compatibility node.

* rtc: omap: restore back (hard-code) wakeup supportHebbar Gururaja2013-07-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | rtc-omap driver modules is used both by OMAP1/2, Davinci SoC platforms. However, rtc wake support on OMAP1 is broken. Hence the device_init_wakeup() was removed from rtc-omap driver and moved to platform board files that supported it (DA850/OMAP-L138). [1] However, recently [2] it was suggested that driver should always do a device_init_wakeup(dev, true). Platforms that don't want/need wakeup support can disable it from userspace via: echo disabled > /sys/devices/.../power/wakeup Also, with the new DT boot-up, board file doesn't exist and hence there is no way to have device wakeup support rtc. The fix for above issues, is to hard code device_init_wakeup() inside driver and let platforms that don't need this, handle it through the sysfs power entry.

| | | | | | | | | | | | | | | | | | | | | | | OMAP1 RTC driver is used in multiple devices like, OMAPL138 and AM33XX. Driver currently doesn't handle any clocks, which may be right for OMAP1 architecture but in case of AM33XX, the clock/module needs to be enabled in order to access the registers.

* rtc: omap: kicker mechanism supportAfzal Mohammed2012-12-181-3/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OMAP RTC IP can have kicker feature. This prevents spurious writes to register. To write to registers kicker lock has to be released. Procedure to do it as follows, 1. write to kick0 register, 0x83e70b13 2. write to kick1 register, 0x95a4f1e0 Writing value other than 0x83e70b13 to kick0 enables write locking, more details about kicker mechanism can be found in section 20.3.3.5.3 of AM335X TRM @www.ti.com/am335x Here id table information is added and is used to distinguish those that require kicker handling and the ones that doesn't need it. There are more features in the newer IP's compared to legacy ones other than kicker, which driver currently doesn't handle, supporting additional features would be easier with the addition of id table. Older IP (of OMAP1) doesn't have revision register as per TRM, so revision register can't be relied always to find features, hence id table is being used. While at it, replace __raw_writeb/__raw_readb with writeb/readb; this driver is used on ARMv7 (AM335X SoC) Signed-off-by: Afzal Mohammed <afzal@ti.com> Acked-by: Sekhar Nori <nsekhar@ti.com> Cc: Grant Likely <grant.likely@secretlab.ca> Cc: Sekhar Nori <nsekhar@ti.com> Cc: Kevin Hilman <khilman@ti.com> Cc: Russell King <linux@arm.linux.org.uk> Cc: Alessandro Zummo <a.zummo@towertech.it> Cc: Daniel Mack <zonque@gmail.com> Cc: Vaibhav Hiremath <hvaibhav@ti.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* RTC: Convert rtc drivers to use the alarm_irq_enable methodJohn Stultz2011-02-031-9/+19
| | | | | | | | | | | | | | | | | | | Some rtc drivers use the ioctl method instead of the alarm_irq_enable method for enabling alarm interupts. With the new virtualized RTC rework, its important for drivers to use the alarm_irq_enable instead. This patch converts the drivers that use the AIE ioctl method to use the alarm_irq_enable method. Other ioctl cmds are left untouched. I have not been able to test or even compile most of these drivers. Any help to make sure this change is correct would be appreciated!

* rtc: omap: let device wakeup capability be configured from chip init logicSekhar Nori2010-10-281-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | The rtc-omap driver currently hardcodes the RTC wakeup capability to be "not capable". While this seems to be true for existing OMAP1 boards which are not wired for this, the DA850/OMAP-L138 SoC, the RTC can always be wake up source from its "deep sleep" mode. This patch lets the wakeup capability be set from platform data and does not override the setting from the driver. For DA850/OMAP-L138, this is done from arch/arm/mach-davinci/devices-da8xx.c:da8xx_register_rtc() Note that this patch does not change the behavior on any existing OMAP1 board since the platform device registration sets the wakeup capability to 0 by default.

* rtc: remove "RTC_ALM_SET mode" bugsDavid Brownell2007-05-081-28/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a common glitch in how RTC drivers handle two "set alarm" modes, by getting rid of the surprising/hidden one that was rarely implemented correctly (and which could expose nonportable hardware-specific behavior). The glitch comes from the /dev/rtcX logic implementing the legacy RTC_ALM_SET (limited to 24 hours, needing RTC_AIE_ON) ioctl on top of the RTC driver call providing access to the newer RTC_WKALM_SET (without those limitations) by initializing the day/month/year fields to be invalid ... that second mode. Now, since few RTC drivers check those fields, and most hardware misbehaves when faced with invalid date fields, many RTC drivers will set bogus alarm times on those RTC_ALM_SET code paths. (Several in-tree drivers have that issue, and I also noticed it with code reviews on several new RTC drivers.) This patch ensures that RTC drivers never see such invalid alarm fields, by moving some logic out of rtc-omap into the RTC_ALM_SET code and adding an explicit check (which will prevent the issue on other code paths).

* rtc: suspend()/resume() restores system clockDavid Brownell2007-05-081-17/+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.

This creates a new RTC-framework driver for the RTC/calendar module found in various OMAP1 chips. (OMAP2 and OMAP3 use external RTCs, like those in TI's multifunction PM companion chips.) It's been in the Linux-OMAP tree for several months now, and other trees before that, so it's quite stable. The most notable issue is that the OMAP IRQ code doesn't yet support the RTC IRQ as a wakeup event. Once that's fixed, a patch will be needed.
