Subject: Re: [PATCH] arm64: dts: rockchip: Add devicetree for the X3568 v4

hmmmm
I think my board doesn't have PCIe clk.
It works fine.

The OEM documentation does say that, and they provide nopcie and pcie images

This is my dmesg for your reference

[    0.336879] phy phy-fe8c0000.phy.7: rockchip_p3phy_rk3568_init:
lock failed 0x6890000, check input refclk and power supply
[    0.338587] rockchip-dw-pcie: probe of 3c0800000.pcie failed with error -110
