If anyone has any objections, please let me know. ------------------ From: Luca Weiss [ Upstream commit 3414f41a13eb41db15c558fbc695466203dca4fa ] Both gpll6 and gpll7 are parented to CXO at 19.2 MHz and not to GPLL0 which runs at 600 MHz. Also gpll6_out_even should have the parent gpll6 and not gpll0. Adjust the parents of these clocks to make Linux report the correct rate and not absurd numbers like gpll7 at ~25 GHz or gpll6 at 24 GHz. Corrected rates are the following: gpll7 807999902 Hz gpll6 768000000 Hz gpll6_out_even 384000000 Hz gpll0 600000000 Hz gpll0_out_odd 200000000 Hz gpll0_out_even 300000000 Hz And because gpll6 is the parent of gcc_sdcc2_apps_clk_src (at 202 MHz) that clock also reports the correct rate now and avoids this warning: [ 5.984062] mmc0: Card appears overclocked; req 202000000 Hz, actual 6312499237 Hz Fixes: 131abae905df ("clk: qcom: Add SM6350 GCC driver") Signed-off-by: Luca Weiss Link: https://lore.kernel.org/r/20240508-sm6350-gpll-fix-v1-1-e4ea34284a6d@fairphone.com Signed-off-by: Bjorn Andersson Signed-off-by: Sasha Levin --- drivers/clk/qcom/gcc-sm6350.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/drivers/clk/qcom/gcc-sm6350.c b/drivers/clk/qcom/gcc-sm6350.c index cf4a7b6e0b23a..0559a33faf00e 100644 --- a/drivers/clk/qcom/gcc-sm6350.c +++ b/drivers/clk/qcom/gcc-sm6350.c @@ -100,8 +100,8 @@ static struct clk_alpha_pll gpll6 = { .enable_mask = BIT(6), .hw.init = &(struct clk_init_data){ .name = "gpll6", - .parent_hws = (const struct clk_hw*[]){ - &gpll0.clkr.hw, + .parent_data = &(const struct clk_parent_data){ + .fw_name = "bi_tcxo", }, .num_parents = 1, .ops = &clk_alpha_pll_fixed_fabia_ops, @@ -124,7 +124,7 @@ static struct clk_alpha_pll_postdiv gpll6_out_even = { .clkr.hw.init = &(struct clk_init_data){ .name = "gpll6_out_even", .parent_hws = (const struct clk_hw*[]){ - &gpll0.clkr.hw, + &gpll6.clkr.hw, }, .num_parents = 1, .ops = &clk_alpha_pll_postdiv_fabia_ops, @@ -139,8 +139,8 @@ static struct clk_alpha_pll gpll7 = { .enable_mask = BIT(7), .hw.init = &(struct clk_init_data){ .name = "gpll7", - .parent_hws = (const struct clk_hw*[]){ - &gpll0.clkr.hw, + .parent_data = &(const struct clk_parent_data){ + .fw_name = "bi_tcxo", }, .num_parents = 1, .ops = &clk_alpha_pll_fixed_fabia_ops, -- 2.43.0
