Chao Xie	5d26c15d3b	clk: mmp: try to use closer one when do round rate ... The orignal code will use the bigger rate between "previous rate" and "current rate" when caculate the rate. In fact, hardware cares about the closest one. So choose the closer rate between "previous rate" and "current rate".

Chao Xie	c45693a648	clk: mmp: fix the wrong calculation formula ... The formula is numerator/denominator = Fin / (Fout * factor) So Fout = Fin * denominator / (numerator * factor). Current clk_factor_round_rate and clk_factor_recalc_rate use wrong formula. This patch will fix them.

Chao Xie	7433ab43fa	clk: mmp: fix wrong mask when calculate denominator ... The code has typo when calculate denominator. It should use den_mask instead of num_mask. Signed-off-by: Chao Xie <chao.xie@marvell.com> Signed-off-by: Mike Turquette <mturquette@linaro.org>	2014-03-26 20:59:26 -07:00
