clk: mmp: try to use closer one when do round rate

2014-03-27T03:59:27+00:00

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". Signed-off-by: Chao Xie Signed-off-by: Mike Turquette

clk: mmp: fix the wrong calculation formula

2014-03-27T03:59:27+00:00

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. Signed-off-by: Chao Xie Signed-off-by: Mike Turquette

clk: mmp: fix wrong mask when calculate denominator

2014-03-27T03:59:26+00:00

The code has typo when calculate denominator. It should use den_mask instead of num_mask. Signed-off-by: Chao Xie Signed-off-by: Mike Turquette

clk: add CLK_SET_RATE_NO_REPARENT flag

2013-08-19T19:27:17+00:00

Add a CLK_SET_RATE_NO_REPARENT clock flag, which will prevent muxes being reparented during clk_set_rate. To avoid breaking existing platforms, all callers of clk_register_mux() are adjusted to pass the new flag. Platform maintainers are encouraged to remove the flag if they wish to allow mux reparenting on set_rate.
