Subject: [PATCH 01/26] ARM: OMAP: dmtimer: Remove setting of clk parent indirectly through platform hook
Date: Thu, 24 Apr 2014 16:43:44 -0500	[thread overview]
Message-ID: <1398375849-6017-2-git-send-email-joelf@ti.com> (raw)
In-Reply-To: <1398375849-6017-1-git-send-email-joelf@ti.com>

There is a platform specific hook just for OMAP1 to set its clk parent.  Remove
this hook and have OMAP1 set its parent in omap1_dm_timer_init.  If OMAP1 is
ever migrated to clock framework, the correct way to do this would be through
clk_set_parent like other platforms.
