2025-03-14drivers: clk: qcom: ipq5424: fix the freq table of sdcc1_apps clockManikanta Mylavarapu1-4/+4
The divider values in the sdcc1_apps frequency table were incorrectly updated, assuming the frequency of gpll2_out_main to be 1152MHz. However, the frequency of the gpll2_out_main clock is actually 576MHz (gpll2/2). Due to these incorrect divider values, the sdcc1_apps clock is running at half of the expected frequency. Fixing the frequency table of sdcc1_apps allows the sdcc1_apps clock to run according to the frequency plan.

2025-02-14clk: qcom: ipq5424: fix software and hardware flow control error of UARTManikanta Mylavarapu1-5/+11
The UART’s software and hardware flow control are currently not functioning correctly. For software flow control, the following error is encountered: qcom_geni_serial 1a80000.serial: Couldn't find suitable clock rate for 56000000, 3500000, 2500000, 1152000, 921600, 19200 During hardware flow control testing, a “Retry 0: Got ZCAN error” is observed. To address these issues, update the UART frequency table to include all supported frequencies according to the frequency plan.

2025-01-07clk: qcom: ipq5424: add gcc_xo_clkManikanta Mylavarapu1-0/+19
The gcc_xo_clk is required for the functionality of the WiFi copy engine block. Therefore, add the gcc_xo_clk in gcc driver.

The gcc_apss_dbg clk is access protected by trust zone, and accessing it results in a kernel crash. Therefore remove the gcc_apss_dbg_clk from the gcc driver.

The newly added driver causes a warnings when enabling -Wunused-const-variables: drivers/clk/qcom/gcc-ipq5424.c:1064:30: error: 'ftbl_gcc_q6_axi_clk_src' defined but not used [-Werror=unused-const-variable=] 1064 | static const struct freq_tbl ftbl_gcc_q6_axi_clk_src[] = { | ^~~~~~~~~~~~~~~~~~~~~~~ drivers/clk/qcom/gcc-ipq5424.c:957:30: error: 'ftbl_gcc_qpic_clk_src' defined but not used [-Werror=unused-const-variable=] 957 | static const struct freq_tbl ftbl_gcc_qpic_clk_src[] = { | ^~~~~~~~~~~~~~~~~~~~~ drivers/clk/qcom/gcc-ipq5424.c:497:30: error: 'ftbl_gcc_qupv3_2x_core_clk_src' defined but not used [-Werror=unused-const-variable=] 497 | static const struct freq_tbl ftbl_gcc_qupv3_2x_core_clk_src[] = { | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In order to hopefully enable this warning by default in the future, remove the data for now. If it gets used in the future, it can trivially get added back.
