+Date: Thu, 22 May 2025 22:25:55 +0200

+
+With the conversion done by commit e88f03230dc0 ("clk: qcom: gcc-ipq8074:
+rework nss_port5/6 clock to multiple conf") a Copy-Paste error was made
+for the nss_port6_tx_clk_src frequency table.
+
+This was caused by the wrong setting of the parent in
+ftbl_nss_port6_tx_clk_src that was wrongly set to P_UNIPHY1_RX instead
+of P_UNIPHY2_TX.
+
+This cause the UNIPHY2 port to malfunction when it needs to be scaled to
+higher clock. The malfunction was observed with the example scenario
+with an Aquantia 10G PHY connected and a speed higher than 1G (example
+2.5G)
+
+Fix the broken frequency table to restore original functionality.
