[PATCH RFC v3 01/18] clk: divider: Correct parent clk round rate if no bestdiv is normally found

If no best divider is normally found, we will try to use the maximum divider. We should not set the parent clock rate to be 1Hz by force for being rounded. Instead, we should take the maximum divider as a base and calculate a correct parent clock rate for being rounded. Signed-off-by: Liu Ying
