  • 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.

  • 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

  • 0683d5035   clocksource/drivers/tango_xtal: 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 leave the caller unaware of 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 returns an error code from the init function.
