Subject: [PATCH 15/26] ARM: OMAP2+: timer: Use of_clk_get for DT platforms
Date: Thu, 24 Apr 2014 16:43:58 -0500 [thread overview]
Message-ID: <1398375849-6017-16-git-send-email-joelf@ti.com> (raw)
In-Reply-To: <1398375849-6017-1-git-send-email-joelf@ti.com>
For DT-booting platforms, use of_clk_get to get the fclk for system timers.
Separate out the legacy code for non-DT platform use.
