|
|
+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.
