Renesas chip has many clocks inside, and some of them are using fixed ratio via parent clock. Current shmobile clock code is using own divX_recalc function and divX_clk_ops. This patch can reduce these code Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Acked-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
