    Subject[PATCH v2 3/5] clocksource: sun5i: Remove sched_clock
    Date
    It's not possible to remove a sched_clock once it has been added, nor is it
    possible to change its rate.

    Since we will need to support a rate change, and that we have other
    sched_clocks in the system anyway, remove it.
