From b4777a21381fd1f87be8c606a616b7f97f485d2b Mon Sep 17 00:00:00 2001 From: Rajendra Nayak Date: Fri, 27 Apr 2012 15:53:48 +0530 Subject: ARM: OMAP3: clock: Convert to common clk Convert all OMAP3 specific platform files to use COMMON clk and keep all the changes under the CONFIG_COMMON_CLK macro check so it does not break any existing code. At a later point switch to COMMON clk and get rid of all old/legacy code.
