  • 172733959   clocksource/drivers: Rename CLOCKSOURCE_OF_DECLARE to TIMER_OF_DECLARE ... Browse Code »

    The CLOCKSOURCE_OF_DECLARE macro is used widely for the timers to declare the
    clocksource at early stage. However, this macro is also used to initialize
    the clockevent if any, or the clockevent only.

    It was originally suggested to declare another macro to initialize a
    clockevent, so in order to separate the two entities even they belong to the
    same IP. This was not accepted because of the impact on the DT where splitting
    a clocksource/clockevent definition does not make sense as it is a Linux
    concept not a hardware description.

    On the other side, the clocksource has not interrupt declared while the
    clockevent has, so it is easy from the driver to know if the description is
    for a clockevent or a clocksource, IOW it could be implemented at the driver
    level.

    So instead of dealing with a named clocksource macro, let's use a more generic
    one: TIMER_OF_DECLARE.

    The patch has not functional changes.

    Pull timer type cleanups from Thomas Gleixner:
    "This series does a tree wide cleanup of types related to
    timers/timekeeping.

    - Get rid of cycles_t and use a plain u64. The type is not really
    helpful and caused more confusion than clarity

    - Get rid of the ktime union. The union has become useless as we use
    the scalar nanoseconds storage unconditionally now. The 32bit
    timespec alike storage got removed due to the Y2038 limitations
    some time ago.

    That leaves the odd union access around for no reason. Clean it up.

    Both changes have been done with coccinelle and a small amount of
    manual mopping up"

    There is no point in having an extra type for extra confusion. u64 is
    unambiguous.

    Conversion was done with the following coccinelle script:

    @rem@

    -typedef u64 cycle_t;

    @fix@
    typedef cycle_t;

    -cycle_t

    When the state names got added a script was used to add the extra argument
    to the calls. The script basically converted the state constant to a
    string, but the cleanup to convert these strings into meaningful ones did
    not happen.

    Replace all the useless strings with 'subsys/xxx/yyy:state' strings which
    are used in all the other places already.

  • 177cf6e52   clocksources: Switch back to the clksrc table ... Browse Code »

    All the clocksource drivers's init function are now converted to return
    an error code. CLOCKSOURCE_OF_DECLARE is no longer used as well as the
    clksrc-of table.

    Let's convert back the names:
    - CLOCKSOURCE_OF_DECLARE_RET => CLOCKSOURCE_OF_DECLARE
    - clksrc-of-ret => clksrc-of

  • ab51189ca   clocksource/drivers/qcom: Convert init function to return error ... Browse Code »

    The init functions do not return any error. They behave as the following:

    - panic, thus leading to a kernel crash while another timer may work and
    make the system boot up correctly

    or

    - print an error and let the caller unaware if the state of the system

    Change that by converting the init functions to return an error conforming
    to the CLOCKSOURCE_OF_RET prototype.

    Proper error handling (rollback, errno value) will be changed later case
    by case, thus this change just return back an error or success in the init
    function.

  • 736b2df2a   clockevents/drivers/qcom: Migrate to new 'set-state' interface ... Browse Code »

    Migrate qcom driver to the new 'set-state' interface provided by
    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.

    Periodic mode isn't supported by the driver and so the callback isn't
    provided anymore.
