  • With the generic RTC rework, the UIE mode irqs are handled
    in the generic layer, and only hardware specific ioctls
    get passed down to the rtc driver layer.

    So this patch removes the UIE mode ioctl handling in the rtc
    driver layer, which never get used.

  • 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!

  • Fix two new-ish runtime warnings in the at91rm9200 (etc) RTC:

    Platform driver 'at91_rtc' needs updating - please use dev_pm_ops
    ... by just switching

    IRQ 1/at91_rtc: IRQF_DISABLED is not guaranteed on shared IRQs
    ... no longer needed now that rtc_update_irq() changed

  • This fixes kernel http://bugzilla.kernel.org/show_bug.cgi?id=11112 (bogus
    RTC update IRQs reported) for rtc-at91rm9200 by scrubbing old IRQ status
    before enabling IRQs.

    It also removes nonfunctional periodic IRQ support from this driver;
    only update IRQs are reported, or provided by the hardware.

    I suspect some other RTCs probably have versions of #11112; it's easy to
    overlook, since most non-RTC drivers don't care about spurious IRQs:
    they're not reported to userspace.

  • On ARM, asm/rtc.h only contains definitions for the predecessor to
    the RTC class support. RTC class drivers should not be including
    this include.

  • asm/mach/time.h is the ARM header file for setting up kernel ticker
    timekeeping (be that the old jiffy interrupt or the new clocksource.)
    RTC drivers have no business using this header file, and in fact do
    not require it.

    Build tested on at91sam9rl, omap and s3c2410 configurations.

  • Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is
    prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable RTC
    platform drivers, to re-enable module auto loading.

  • 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().

  • This patch removes class_device from the programming interface that the RTC
    framework exposes to the rest of the kernel. Now an rtc_device is passed,
    which is more type-safe and streamlines all the relevant code.

  • 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.

    Among other things, the init and alarm changes ensure that this driver
    handles the new sysfs "wakealarm" attribute properly.

  • Fix a glitch in the procfs dumping of whether the alarm IRQ is enabled: use
    the traditional name (from drivers/char/rtc.c and many other places) of
    "alarm_IRQ", not "alrm_wakeup" (which didn't even match the efirtc code, which
    originated that reporting API).

    Also, update a few of the RTC drivers to stop providing that duplicate status,
    and/or to expose it properly when reporting the alarm state. We really don't
    want every RTC driver doing their own thing here...

  • The new Atmel AT91SAM9261 and AT91SAM9260 processors do not have the
    internal RTC peripheral. This RTC driver is therefore
    AT91RM9200-specific.

    This patch renames rtc-at91.c to rtc-at91rm9200.c, and changes the name
    of the configuration option.
