- * it will be cleared in sleep which makes it unsuitable.
- * We however need it as a timer tick (clockevent)
- * during boot to calibrate delay until twd is started.
- * RTC-RTT have problems as timer tick during boot since it is
- * depending on delay which is not yet calibrated. RTC-RTT is in the
- * always-on powerdomain and is used as clockevent instead of twd when
- * sleeping.
- * The PRCMU timer 4(3 for DB5500) register a clocksource and
- * sched_clock with higher rating then MTU since is always-on.
