  • ebe753357   drivers/rtc/rtc-s3c.c: remove NO_IRQ macro ... Browse Code »

    NO_IRQ may be defined as '(unsigned int) -1' in some architectures (arm,
    sh ...), and either may not be defined in some architectures (arm64) which
    can enable RTC_DRV_S3C.

    Also since platform_get_irq returns err-code in case of any error, we do
    not need to intialize s3c_rtc_alarmno and s3c_rtc_tickno.

    The driver core clears the driver data to NULL after device_release or
    on probe failure, since commit 0998d063100 ("device-core: Ensure drvdata
    = NULL when no driver is bound"). Thus, it is not needed to manually
    clear the device driver data to NULL.

    We're getting close to having most of them converted!

    One of the larger platforms remaining is Samsung Exynos, and there are
    a bunch of supporting patches in this merge window for it. There was
    a patch in this branch to a early version of multiplatform conversion,
    but it ended up being reverted due to need of more bake time. The
    revert commit is part of the branch since it would have required
    rebasing multiple dependent branches and they were stable by then"

    Nothing outside of the rtc driver includes plat/regs-rtc.h,
    so we can simply move the file into the same directory,
    which allows us to build the file as platform-independent

    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.

    Since commit e58aa3d2d0cc ("genirq: run irq handlers with interrupts

    even check and yell when an interrupt handler returns with interrupts
    enabled - see commit b738a50a2026 ("genirq: warn when handler enables

    So now this flag is a NOOP and can be removed.

  • 88cee8fd7   drivers/rtc/rtc-s3c.c: fix no occurrence of alarm interrupt ... Browse Code »

    The driver does not generate an alarm interrupt even though a time for
    an alarm is set.

    This results from disabling rtc_clk after setting the alarm time.

    To generate an alarm interrupt the driver should maintain its enabled
    state for rtc_clk the until alarm interrupt occurs. This patch permits
    generation of an alarm interrupt.

  • 62d176018   drivers/rtc/rtc-s3c.c: allow multiple open / allow no-ioctl-open'ed rtc to have irq. ... Browse Code »

    The previous rtc-s3c had two issues related with its IRQ.

    1. Users cannot open rtc multiple times because an open operation
    calls request_irq on the same IRQ. (e.g., two user processes wants to
    open and read RTC time from rtc-s3c at the same time)

    2. If alarm is set and no one has the rtc opened with filesystem
    (either the alarm is set by kernel/boot-loader or user set an alarm and
    closed rtc dev file), the pending bit is not cleared and no further
    interrupt is invoked. When the alarm is used by the system itself such
    as a resume from suspend-to-RAM or other Low-power modes/idle, this is
    a critical issue.

    This patch mitigates these issues by calling request_irq at probe and
    free_irq at remove.
