You're missing the resets:

			resets = <&infracfg_ao MT8195_INFRA_RST2_PCIE_P0_SWRST>;
			reset-names = "mac";

Here too:

				 <&infracfg_ao MT8195_INFRA_RST2_PCIE_P1_SWRST>;

Please run dtbs_check and try to build the kernel before pushing commits upstream.
This will give you a not-so-nice warning and that shall not happen.

You can solve it by naming these nodes like:
pciephy-rx-ln1@190,1
pciephy-tx-ln1-nmos@190,2

...etc

Angelo

Hi Angelo,

Thanks for your review.

Reset the combo-phy in PCIe driver will cause side effect on USB2 port,
so this reset cannot be added.

We will fix others in the next version.

Thanks.
