PCIe: SERDES output reference clock cannot be used
The PCIe Reference Clock Output of the SERDES does not comply with the certain PCI-SIG specifications, which may cause issues for external PCIe components receiving and using the reference clock. Therefore, SERDES reference clock (signals SERDES0_REFCLK0P and SERDES0_REFCLK0N) cannot be used to output a PCIe reference clock.
None. This issue is still under investigation.
