Custom board with RK3568: problem with PCI-E

[Pasha-From-Russia]

Hello
I'm trying to run pci-e on my board with RK35368 CPU. I took rockchip-linux/kernel (branch develop-5.10), rockchip-linux/u-boot (branch next-dev )

my dts file is

};

&pcie3x1 {
	status = "okay";
	num-lanes = <1>;

};

&pcie3x2 {

	num-lanes = <1>;
	vpcie3v3-supply = <&vcc3v3_pcie>;
};

i also added a u-boot patch from here

my kernel says the following errors:
