Subject: [PATCH 2/2] ARM: dts: gr-peach: Enable ostm0 and ostm1 timers
Date: Mon,  9 Oct 2017 10:48:35 +0200	[thread overview]
Message-ID: <1507538915-16566-3-git-send-email-jacopo+renesas@jmondi.org> (raw)
In-Reply-To: <1507538915-16566-1-git-send-email-jacopo+renesas@jmondi.org>

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
