[PATCH 04/29] ARM: omap: clk: use clk_prepare_enable and clk_disable_unprepare
Rajendra Nayak

Thu Jun 14 08:46:53 EDT 2012
As we move to Common clk framework use clk_prepare_enable()
instead of clk_enable() and similarly clk_disable_unprepare()
instead of clk_disable()
Based on initial changes from Mike turquette.
