I thought I fixed those! Looking closer at the fix, I see that I totally bungled it (or at least I halfway bungled it). The SD card clock got fixed (and that was the one I was really focused on fixing), but I totally adjusted the wrong clock for eMMC. Sigh. Let's fix my dumb mistake. Now both SD and eMMC have floor for the "apps" clock. This doesn't matter a lot for the final clock rate for HS400 eMMC but could matter if someone happens to put some slower eMMC on a sc7180. We also transition through some of these lower rates sometimes and having them wrong could cause problems during these transitions. These were the messages I was seeing at boot: mmc1: Card appears overclocked; req 52000000 Hz, actual 100000000 Hz mmc1: Card appears overclocked; req 52000000 Hz, actual 100000000 Hz mmc1: Card appears overclocked; req 104000000 Hz, actual 192000000 Hz Fixes: 6d37a8d19283 ("clk: qcom: gcc-sc7180: Use floor ops for sdcc clks") Signed-off-by: Douglas Anderson Link: https://lore.kernel.org/r/20210224095013.1.I2e2ba4978cfca06520dfb5d757768f9c42140f7c@changeid Reviewed-by: Taniya Das Signed-off-by: Stephen Boyd Signed-off-by: Sasha Levin --- drivers/clk/qcom/gcc-sc7180.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/clk/qcom/gcc-sc7180.c b/drivers/clk/qcom/gcc-sc7180.c index 88e896abb663..da8b627ca156 100644 --- a/drivers/clk/qcom/gcc-sc7180.c +++ b/drivers/clk/qcom/gcc-sc7180.c @@ -620,7 +620,7 @@ static struct clk_rcg2 gcc_sdcc1_apps_clk_src = { .name = "gcc_sdcc1_apps_clk_src", .parent_data = gcc_parent_data_1, .num_parents = 5, - .ops = &clk_rcg2_ops, + .ops = &clk_rcg2_floor_ops, }, }; @@ -642,7 +642,7 @@ static struct clk_rcg2 gcc_sdcc1_ice_core_clk_src = { .name = "gcc_sdcc1_ice_core_clk_src", .parent_data = gcc_parent_data_0, .num_parents = 4, - .ops = &clk_rcg2_floor_ops, + .ops = &clk_rcg2_ops, }, }; -- 2.30.1
