Subject: [PATCH V2] ARM: dts: DRA7: provide arch-timer frequenecy parameter
Date: Tue, 17 Sep 2013 12:01:28 -0500 [thread overview]
Message-ID: <1379437288-10831-1-git-send-email-nm@ti.com> (raw)
In-Reply-To: <5238899D.60903-l0cyMroinI0@public.gmane.org>
CNTFREQ isn't pre-programmed on DRA7 just like O5, so provide the
timer frequency via DT. Without a valid value arch_timer_init results
in div0 crash.
