  • 9f475d084   clocksource: Remove dev_err() usage after platform_get_irq() ... Browse Code »

    We don't need dev_err() messages when platform_get_irq() fails now that
    platform_get_irq() prints an error message itself when something goes
    wrong. Let's remove these prints with a simple semantic patch.

    //
    @@
    expression ret;
    struct platform_device *E;
    @@

    ret =
    (
    platform_get_irq(E, ...)
    |
    platform_get_irq_byname(E, ...)
    );

    if ( \( ret < 0 \| ret

    While we're here, remove braces on if statements that only have one
    statement (manually).

  • 4e53aa2fd   clocksource: em_sti: Compute rate before registration ... Browse Code »

    With the upcoming NTP correction related rate adjustments to be implemented
    in the clockevents core, the latter needs to get informed about every rate
    change of a clockevent device made after its registration.

    Currently, em_sti violates this requirement in that it registers its
    clockevent device with a dummy rate and sets its final rate through
    clockevents_config() called from its ->set_state_oneshot().

    This patch moves the setting of the clockevent device's rate to its
    registration.

    I checked all current em_sti users in arch/arm/mach-shmobile and right now,
    none of them changes any rate in any clock tree relevant to em_sti after
    their respective time_init(). Since all em_sti instances are created after
    time_init(), none of them should ever observe any clock rate changes.

    - Determine the ->rate value in em_sti_probe() at device probing rather
    than at first usage.
    - Set the clockevent device's rate at its registration.
    - Although not strictly necessary for the upcoming clockevent core changes,
    set the clocksource's rate at its registration for consistency.

  • 3814ae092   clocksource: em_sti: Split clock prepare and enable steps ... Browse Code »

    Currently, the em_sti driver prepares and enables the needed clock in
    em_sti_enable(), potentially called through its clockevent device's
    ->set_state_oneshot().

    However, the clk_prepare() step may sleep whereas tick_program_event() and
    thus, ->set_state_oneshot(), can be called in atomic context.

    Split the clk_prepare_enable() in em_sti_enable() into two steps:
    - prepare the clock at device probing via clk_prepare()
    - and enable it in em_sti_enable() via clk_enable().
    Slightly reorder resource initialization in em_sti_probe() in order to
    facilitate error handling in later patches.

  • 75f940615   clockevents/drivers/em_sti: Migrate to new 'set-state' interface ... Browse Code »

    Migrate em_sti driver to the new 'set-state' interface provided by
    the clockevents core, the earlier 'set-mode' interface is marked
    obsolete now.

    This also enables us to implement callbacks for new states of clockevent
    devices, for example: ONESHOT_STOPPED.

    NOTE: This also drops a special check:

    if (old_mode == CLOCK_EVT_MODE_ONESHOT)
    em_sti_stop(p, USER_CLOCKEVENT);

    as it doesn't look like that important. This driver only supports
    ONESHOT and we can only move only to SHUTDOWN from ONESHOT and.
    Also on second call (on shutdown), em_sti_stop() would return without
    disabling the device again.

  • fba9e0720   clocksource: Rename __clocksource_updatefreq_*() to __clocksource_update_freq_*() ... Browse Code »

    Ingo requested this function be renamed to improve readability,
    so I've renamed __clocksource_updatefreq_scale() as well as the
    __clocksource_updatefreq_hz/khz() functions to avoid
    squishedtogethernames.

    This touches some of the sh clocksources, which I've not tested.

    The arch/arm/plat-omap change is just a comment change for
    consistency.

  • 2199a5574   clocksource: em_sti: Set cpu_possible_mask to fix SMP broadcast ... Browse Code »

    Update the STI driver by setting cpu_possible_mask to make EMEV2
    SMP work as expected together with the ARM broadcast timer.

    This breakage was introduced by:

    f7db706 ARM: 7674/1: smp: Avoid dummy clockevent being preferred over real hardware clock-event

    Without this fix SMP operation is broken on EMEV2 since no
    broadcast timer interrupts trigger on the secondary CPU cores.

  • 09acc3a1e   clocksource: em_sti: Set initcall level to subsys ... Browse Code »

    The reason for this is to ensure that STI is probed earlier
    than with its previous initcall level, module init.

    This came up as a problem with using CMT as a clock source kzm9g-reference
    which does not make use of early timers or devices. In that scenario
    initialisation of SDHI and MMCIF both stall on msleep() calls due to the
    absence of a initialised clock source.

    The purpose of this change is to keep the STI code in sync with the CMT code
    which has been modified in a similar manner..

    Boot tested on: kzm9d.

  • 1850514b3   Drivers: clocksource: 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.

  • b9dbf9517   clocksource: em_sti: Emma Mobile STI driver ... Browse Code »

    The STI hardware is based on a single 48-bit 32kHz
    counter that together with two individual compare
    registers can generate interrupts. There are no
    timer operating modes selectable which means that
    the timer can not clear on match.

    This driver is providing clocksource support for the
    48-bit counter. Clockevents are also supported using
    the same timer in oneshot mode.
