[PATCH 2/2] ARM: dts: gr-peach: Enable ostm0 and ostm1 timers

From: Jacopo Mondi
Date: Mon Oct 09 2017 - 04:49:13 EST


Enable ostm0 and ostm1 timers to be used as clock source and clockevent
source. The timers provides greater accuracy than the already enabled
mtu2 one.

With these enabled:

clocksource: ostm: mask: 0xffffffff max_cycles: 0xffffffff, max_idle_ns: 57352151442 ns
sched_clock: 32 bits at 33MHz, resolution 30ns, wraps every 64440619504ns
ostm: used for clocksource
ostm: used for clock events
