The CMN PLL controller provides clocks to networking hardware blocks
on Qualcomm IPQ9574 SoC. It receives input clock from the on-chip Wi-Fi,
and produces output clocks at fixed rates. These output rates are
predetermined, and are unrelated to the input clock rate. The output
clocks are supplied to the Ethernet hardware such as PPE (packet
process engine) and the externally connected switch or PHY device.

You did not explain what is CMN. Is this some sort of acronym?
Best regards,
