    MIPS: clockevent drivers: Set ->min_delta_ticks and ->max_delta_ticks · e4db9253
    Nicolai Stange authored
    In preparation for making the clockevents core NTP correction aware,
    all clockevent device drivers must set ->min_delta_ticks and
    ->max_delta_ticks rather than ->min_delta_ns and ->max_delta_ns: a
    clockevent device's rate is going to change dynamically and thus, the
    ratio of ns to ticks ceases to stay invariant.
    
    Make the MIPS arch's clockevent drivers initialize these fields properly.
    
    This patch alone doesn't introduce any change in functionality as the
    clockevents core still looks exclusively at the (untouched) ->min_delta_ns
    and ->max_delta_ns. As soon as this has changed, a followup patch will
    purge the initialization of ->min_delta_ns and ->max_delta_ns from these
    drivers.
