    clockevents/drivers/sh_cmt: Set ->min_delta_ticks and ->max_delta_ticks · bb2e94ac
    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 sh_cmt clockevent driver 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 this
    driver.
