From 631c54f07d7848843f9f1853e40342a033ab1666 Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Wed, 24 Apr 2024 04:39:31 +0300 Subject: [PATCH] clk: qcom: dispcc-sm8550: fix DisplayPort clocks [ Upstream commit e90b5139da8465a15c3820b4b67ca9468dce93b4 ] On SM8550 DisplayPort link clocks use frequency tables inherited from the vendor kernel, it is not applicable in the upstream kernel. Drop frequency tables and use clk_byte2_ops for those clocks. This fixes frequency selection in the OPP core (which otherwise attempts to use invalid 810 KHz as DP link rate), also fixing the following message: msm-dp-display ae90000.displayport-controller: _opp_config_clk_single: failed to set clock rate: -22 Fixes: 90114ca11476 ("clk: qcom: add SM8550 DISPCC driver") Reviewed-by: Neil Armstrong Tested-by: Neil Armstrong # on SM8550-HDK Reviewed-by: Konrad Dybcio Signed-off-by: Dmitry Baryshkov Link: https://lore.kernel.org/r/20240424-dispcc-dp-clocks-v2-3-b44038f3fa96@linaro.org Signed-off-by: Bjorn Andersson Signed-off-by: Sasha Levin --- drivers/clk/qcom/dispcc-sm8550.c | 20 ++++---------------- 1 file changed, 4 insertions(+), 16 deletions(-) diff --git a/drivers/clk/qcom/dispcc-sm8550.c b/drivers/clk/qcom/dispcc-sm8550.c index 0b8f0904b339..b9edeb2a221d 100644 --- a/drivers/clk/qcom/dispcc-sm8550.c +++ b/drivers/clk/qcom/dispcc-sm8550.c @@ -345,26 +345,17 @@ static struct clk_rcg2 disp_cc_mdss_dptx0_aux_clk_src = { }, }; -static const struct freq_tbl ftbl_disp_cc_mdss_dptx0_link_clk_src[] = { - F(162000, P_DP0_PHY_PLL_LINK_CLK, 1, 0, 0), - F(270000, P_DP0_PHY_PLL_LINK_CLK, 1, 0, 0), - F(540000, P_DP0_PHY_PLL_LINK_CLK, 1, 0, 0), - F(810000, P_DP0_PHY_PLL_LINK_CLK, 1, 0, 0), - { } -}; - static struct clk_rcg2 disp_cc_mdss_dptx0_link_clk_src = { .cmd_rcgr = 0x8170, .mnd_width = 0, .hid_width = 5, .parent_map = disp_cc_parent_map_7, - .freq_tbl = ftbl_disp_cc_mdss_dptx0_link_clk_src, .clkr.hw.init = &(struct clk_init_data) { .name = "disp_cc_mdss_dptx0_link_clk_src", .parent_data = disp_cc_parent_data_7, .num_parents = ARRAY_SIZE(disp_cc_parent_data_7), .flags = CLK_SET_RATE_PARENT, - .ops = &clk_rcg2_ops, + .ops = &clk_byte2_ops, }, }; @@ -418,13 +409,12 @@ static struct clk_rcg2 disp_cc_mdss_dptx1_link_clk_src = { .mnd_width = 0, .hid_width = 5, .parent_map = disp_cc_parent_map_3, - .freq_tbl = ftbl_disp_cc_mdss_dptx0_link_clk_src, .clkr.hw.init = &(struct clk_init_data) { .name = "disp_cc_mdss_dptx1_link_clk_src", .parent_data = disp_cc_parent_data_3, .num_parents = ARRAY_SIZE(disp_cc_parent_data_3), .flags = CLK_SET_RATE_PARENT, - .ops = &clk_rcg2_ops, + .ops = &clk_byte2_ops, }, }; @@ -478,13 +468,12 @@ static struct clk_rcg2 disp_cc_mdss_dptx2_link_clk_src = { .mnd_width = 0, .hid_width = 5, .parent_map = disp_cc_parent_map_3, - .freq_tbl = ftbl_disp_cc_mdss_dptx0_link_clk_src, .clkr.hw.init = &(struct clk_init_data) { .name = "disp_cc_mdss_dptx2_link_clk_src", .parent_data = disp_cc_parent_data_3, .num_parents = ARRAY_SIZE(disp_cc_parent_data_3), .flags = CLK_SET_RATE_PARENT, - .ops = &clk_rcg2_ops, + .ops = &clk_byte2_ops, }, }; @@ -538,13 +527,12 @@ static struct clk_rcg2 disp_cc_mdss_dptx3_link_clk_src = { .mnd_width = 0, .hid_width = 5, .parent_map = disp_cc_parent_map_3, - .freq_tbl = ftbl_disp_cc_mdss_dptx0_link_clk_src, .clkr.hw.init = &(struct clk_init_data) { .name = "disp_cc_mdss_dptx3_link_clk_src", .parent_data = disp_cc_parent_data_3, .num_parents = ARRAY_SIZE(disp_cc_parent_data_3), .flags = CLK_SET_RATE_PARENT, - .ops = &clk_rcg2_ops, + .ops = &clk_byte2_ops, }, };
