Subject: [PATCH] ARM: dts: DRA7: provide arch-timer frequenecy parameter
Date: Tue, 17 Sep 2013 11:47:13 -0500	[thread overview]
Message-ID: <1379436433-24914-1-git-send-email-nm@ti.com> (raw)

CNTFREQ isn't pre-programmed on DRA7 just like O5, so provide the
same. Without a valid value arch_timer_init results in div0 crash.
Providing the same is a safer alternative.
