    ARM: OMAP2+: Get rid of custom OMAP_32K_TIMER_HZ · 8f0de0d6

    The timekeeping doesn't depend on HZ value in presence of fine grained
    clocksource and hence there should not be any time drift because of HZ
    value which was chosen to be divisor of 32768.
    
    OMAP has been using HZ = 128 value to avoid any time drift issues
    because of 32768 HZ clock. But with various measurements performed
    with HZ = 100, no time drift is observed and it also proves the
    point about HZ not having impact on time keeping on OMAP.
    
    Very informative thread on this topic is here:
