As the parent are shared +across multiple port it may be required to select the correct +configuration to accomplish the desired clock. Without this patch such +port doesn't work in some specific ethernet speed as the clock will be +set to the wrong frequency as we just select the first configuration for +the related frequency instead of selecting the best one. + +Tested-by: Robert Marko <robimarko@gmail.com> # ipq8074 Qnap QHora-301W +Signed-off-by: Christian Marangi <ansuelsmth@gmail.com> +--- + drivers/clk/qcom/gcc-ipq8074.c | 64 +++++++++++++++++++++++++--------- + 1 file changed, 48 insertions(+), 16 deletions(-) + +--- a/drivers/clk/qcom/gcc-ipq8074.c ++++ b/drivers/clk/qcom/gcc-ipq8074.c +@@ -1676,13 +1676,21 @@ static struct clk_regmap_div nss_port4_t + }, + }; + ++static const struct freq_conf ftbl_nss_port5_rx_clk_src_25[] = { ++ C(P_UNIPHY1_RX, 12.5, 0, 0), ++ C(P_UNIPHY0_RX, 5, 0, 0), ++}; ++ ++static const struct freq_conf ftbl_nss_port5_rx_clk_src_125[] = { ++ C(P_UNIPHY1_RX, 2.5, 0, 0), ++ C(P_UNIPHY0_RX, 1, 0, 0), ++}; ++ + static const struct freq_tbl ftbl_nss_port5_rx_clk_src[] = { + F(19200000, P_XO, 1, 0, 0), +- F(25000000, P_UNIPHY1_RX, 12.5, 0, 0), +- F(25000000, P_UNIPHY0_RX, 5, 0, 0), ++ FM(25000000, ftbl_nss_port5_rx_clk_src_25), + F(78125000, P_UNIPHY1_RX, 4, 0, 0), +- F(125000000, P_UNIPHY1_RX, 2.5, 0, 0), +- F(125000000, P_UNIPHY0_RX, 1, 0, 0), ++ FM(125000000, ftbl_nss_port5_rx_clk_src_125), + F(156250000, P_UNIPHY1_RX, 2, 0, 0), + F(312500000, P_UNIPHY1_RX, 1, 0, 0), + { } +@@ -1738,13 +1746,21 @@ static struct clk_regmap_div nss_port5_r + }, + }; + ++static struct freq_conf ftbl_nss_port5_tx_clk_src_25[] = { ++ C(P_UNIPHY1_TX, 12.5, 0, 0), ++ C(P_UNIPHY0_TX, 5, 0, 0), ++}; ++ ++static struct freq_conf ftbl_nss_port5_tx_clk_src_125[] = { ++ C(P_UNIPHY1_TX, 2.5, 0, 0), ++ C(P_UNIPHY0_TX, 1, 0, 0), ++}; ++ + static const struct freq_tbl ftbl_nss_port5_tx_clk_src[] = { + F(19200000, P_XO, 1, 0, 0), +- F(25000000, P_UNIPHY1_TX, 12.5, 0, 0), +- F(25000000, P_UNIPHY0_TX, 5, 0, 0), ++ FM(25000000, ftbl_nss_port5_tx_clk_src_25), + F(78125000, P_UNIPHY1_TX, 4, 0, 0), +- F(125000000, P_UNIPHY1_TX, 2.5, 0, 0), +- F(125000000, P_UNIPHY0_TX, 1, 0, 0), ++ FM(125000000, ftbl_nss_port5_tx_clk_src_125), + F(156250000, P_UNIPHY1_TX, 2, 0, 0), + F(312500000, P_UNIPHY1_TX, 1, 0, 0), + { } +@@ -1800,13 +1816,21 @@ static struct clk_regmap_div nss_port5_t + }, + }; + ++static struct freq_conf ftbl_nss_port6_rx_clk_src_25[] = { ++ C(P_UNIPHY2_RX, 5, 0, 0), ++ C(P_UNIPHY2_RX, 12.5, 0, 0), ++}; ++ ++static struct freq_conf ftbl_nss_port6_rx_clk_src_125[] = { ++ C(P_UNIPHY2_RX, 1, 0, 0), ++ C(P_UNIPHY2_RX, 2.5, 0, 0), ++}; ++ + static const struct freq_tbl ftbl_nss_port6_rx_clk_src[] = { + F(19200000, P_XO, 1, 0, 0), +- F(25000000, P_UNIPHY2_RX, 5, 0, 0), +- F(25000000, P_UNIPHY2_RX, 12.5, 0, 0), ++ FM(25000000, ftbl_nss_port6_rx_clk_src_25), + F(78125000, P_UNIPHY2_RX, 4, 0, 0), +- F(125000000, P_UNIPHY2_RX, 1, 0, 0), +- F(125000000, P_UNIPHY2_RX, 2.5, 0, 0), ++ FM(125000000, ftbl_nss_port6_rx_clk_src_125), + F(156250000, P_UNIPHY2_RX, 2, 0, 0), + F(312500000, P_UNIPHY2_RX, 1, 0, 0), + { } +@@ -1857,13 +1881,21 @@ static struct clk_regmap_div nss_port6_r + }, + }; + ++static struct freq_conf ftbl_nss_port6_tx_clk_src_25[] = { ++ C(P_UNIPHY2_TX, 5, 0, 0), ++ C(P_UNIPHY2_TX, 12.5, 0, 0), ++}; ++ ++static struct freq_conf ftbl_nss_port6_tx_clk_src_125[] = { ++ C(P_UNIPHY2_TX, 1, 0, 0), ++ C(P_UNIPHY2_TX, 2.5, 0, 0), ++}; ++ + static const struct freq_tbl ftbl_nss_port6_tx_clk_src[] = { + F(19200000, P_XO, 1, 0, 0), +- F(25000000, P_UNIPHY2_TX, 5, 0, 0), +- F(25000000, P_UNIPHY2_TX, 12.5, 0, 0), ++ FM(25000000, ftbl_nss_port6_tx_clk_src_25), + F(78125000, P_UNIPHY2_TX, 4, 0, 0), +- F(125000000, P_UNIPHY2_TX, 1, 0, 0), +- F(125000000, P_UNIPHY2_TX, 2.5, 0, 0), ++ FM(125000000, ftbl_nss_port6_tx_clk_src_125), + F(156250000, P_UNIPHY2_TX, 2, 0, 0), + F(312500000, P_UNIPHY2_TX, 1, 0, 0), + { } |
