Hi, NXP

A Si52112-B3 pcie clock generator is used in my iMX7D based board with Linux-4.9.11 kernel. 100MHz PCIE_REFCLKIN_P/N waveform is shown as follows:

PCIE_REFCLKIN_P/N

After kernel booting up, I got following message about pcie driver loading:

pcie phy pll can't be locked

As my understood, PCIE_PHY is not work properly, but can not figure out what issue with it.

It's appreciated for any help about this issue. Thanks!

BTW, the same kernel can run on iMX7D Sabre Board, and PCIE interface works fine with NVMe module.
