If anyone has any objections, please let me know. ------------------ From: Dmitry Baryshkov [ Upstream commit e801038a02ce1e8c652a0b668dd233a4ee48aeb7 ] On SM8450 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: 16fb89f92ec4 ("clk: qcom: Add support for Display Clock Controller on SM8450") Reviewed-by: Neil Armstrong Reviewed-by: Konrad Dybcio Signed-off-by: Dmitry Baryshkov Link: https://lore.kernel.org/r/20240424-dispcc-dp-clocks-v2-1-b44038f3fa96@linaro.org Signed-off-by: Bjorn Andersson Signed-off-by: Sasha Levin --- drivers/clk/qcom/dispcc-sm8450.c | 20 ++++---------------- 1 file changed, 4 insertions(+), 16 deletions(-) diff --git a/drivers/clk/qcom/dispcc-sm8450.c b/drivers/clk/qcom/dispcc-sm8450.c index 2c4aecd75186b..239cc726c7e29 100644 --- a/drivers/clk/qcom/dispcc-sm8450.c +++ b/drivers/clk/qcom/dispcc-sm8450.c @@ -309,26 +309,17 @@ 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 = 0x819c, .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_dptx0_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, }, }; @@ -382,13 +373,12 @@ 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, }, }; @@ -442,13 +432,12 @@ 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, }, }; @@ -502,13 +491,12 @@ 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, }, }; -- 2.43.0
