This moves the call of davinci_clk_init() from map_io to init_time for all boards. This is the proper place to init clocks. This is also done in preparation for moving to the common clock framework. dm646x is a special case because we need to handle different ref_clk rates depending on which board is being used. The clock init in this case is modified to set the rate before registering the clocks instead of using davinci_set_refclk_rate() to recalculate the entire clock tree after all of the clocks are registered. Also, the cpu_clks field is removed from struct davinci_soc_info since it is no longer needed. Signed-off-by: David Lechner <david@lechnology.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>
