  • db96d571a   rtc: tps65910: allow using RTC without alarm interrupt ... Browse Code »

    If tps65910 INT1 pin (IRQ output) is not wired to any IRQ controller,
    then it can't be used as system wakeup/alarm source,
    but it is still possible to read/write time from/to RTC.

    tps65910 RTC IRQ is nested threaded and wired to the tps65910 inerrupt
    controller. So, this flag is not required for nested irqs anymore,
    since commit 3c646f2c6aa9 ("genirq: Don't suspend nested_thread irqs
    over system suspend") was merged.

    The interrupt handler gets the driver data associated with the RTC
    device and doesn't check it for validity. This can cause a NULL pointer
    being dereferenced when and interrupt fires before the driver data was
    properly set up.

    Fix this by setting the driver data earlier (before the interrupt is
    requested).

  • 225ccc287   drivers/rtc/rtc-tps65910.c: set irq flag to IRQF_EARLY_RESUME during irq request ... Browse Code »

    All interrupt get disabled during system suspend and enabled during system
    resume. 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.

  • dfaf09ac8   drivers/rtc/rtc-tps65910.c: remove unnecessary irq stat save and restore ... Browse Code »

    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.

  • 5a167f454   Drivers: rtc: remove __dev* attributes. ... Browse Code »

    CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
    markings need to be removed.

    This change removes the use of __devinit, __devexit_p, __devinitdata,
    __devinitconst, and __devexit from these drivers.

    Based on patches originally written by Bill Pemberton, but redone by me
    in order to handle some of the coding style issues better, by hand.

    Enabling RTC HW block depends on the default value of TPS65910 register.
    In some mode, RTC block is disabled by default.(eg. AM3517 Craneboard) In
    this case, RTC_PWDN(RTC power down) bit should be cleared to enable the
    RTC HW block.

    This patch also works in case that RTC block is active by default, because
    there is no side effect even if the bit is updated again.

    Tested on AM3517 Craneboard.

    The tps65910_rtc data is registered as the platform driver data in
    _probe(= ). Therefore the tps65910_rtc should be used on unregistering
    the rtc device. And device pointer should be retrieved from the
    platform_device structure.

    This patch fixes the below oops:
