    One method would be to use an init call from <linux/init.h> which is
    called before these are done (you'll have to work out which one is
    suitable for yourself).

    Either that or ensure that your boards always call a specific
    routine in their init sequence to ensure clocks are registered before
    the timer needs them.

    If I remeber correctly, map_io() is actually called before the timers
    are initialised, so you could add your clocks there.
