Subject: [PATCH 05/16] OMAP3: PM: Export get_vdd1_opp and get_vdd2_opp from shared resource framework
Date: Wed, 24 Feb 2010 14:59:06 +0530	[thread overview]
Message-ID: <1267003757-22456-6-git-send-email-thara@ti.com> (raw)
In-Reply-To: <1267003757-22456-5-git-send-email-thara@ti.com>

get_vdd1_opp and get_vdd2_opp APIs will be needed by voltage.c
and smartreflex-class3.c which will get added in the later patches
in this patch series. So it is very clumsy to declare these API's
in each of these files and employ the mechanism of getting the opp
from mpu and l3 clocks.
This patch removes get_vdd1_opp and get_vdd2_opp from smartreflex.c.
To keep the implementaion clean these functions are exported out
in resource34xx.c.
