Subject: [PATCH 1/8] ARM: OMAP2+: timer: Add a powerup function
Date: Tue, 22 Apr 2014 20:27:02 -0500	[thread overview]
Message-ID: <1398216429-4681-2-git-send-email-joelf@ti.com> (raw)
In-Reply-To: <1398216429-4681-1-git-send-email-joelf@ti.com>

In an effort to isolate the time power initialization for future purposes, add
a function to do the same. This primarily involves a hwmod lookup, setup and
enable.
