Some factor clocks, mostly PLLs, have an extra fixed divider just before the clock output. Add an option to the factor clk driver config data to specify this divider.Signed-off-by: Chen-Yu Tsai <w...@csie.org> --- drivers/clk/sunxi/clk-factors.c | 3 +++ drivers/clk/sunxi/clk-factors.h | 1 + 2 files changed, 4 insertions(+) diff --git a/drivers/clk/sunxi/clk-factors.c b/drivers/clk/sunxi/clk-factors.c index 2057c8a..435111d 100644 --- a/drivers/clk/sunxi/clk-factors.c +++ b/drivers/clk/sunxi/clk-factors.c @@ -64,6 +64,9 @@ static unsigned long clk_factors_recalc_rate(struct clk_hw *hw, /* Calculate the rate */ rate = (parent_rate * (n + config->n_start) * (k + 1) >> p) / (m + 1); + if (config->post_div) + rate /= config->post_div; + return rate; } diff --git a/drivers/clk/sunxi/clk-factors.h b/drivers/clk/sunxi/clk-factors.h index d2d0efa..ce70c65 100644 --- a/drivers/clk/sunxi/clk-factors.h +++ b/drivers/clk/sunxi/clk-factors.h @@ -16,6 +16,7 @@ struct clk_factors_config { u8 pshift; u8 pwidth; u8 n_start; + u8 post_div; }; struct clk_factors {
For the record, I liked your solution on[1] more, as it's in line with what we're doing on the other sunxi platforms, instead of adding features in factors to cover for some cases. But it's your and Maxime's call, as I haven't written any of the sun6i code so far.
