PCIe problem on RK3568 EVB

[Doug Brewer]

Hello,

I added the following lines in rk3568-evb1-v10.dts:

pcie30_avdd0v9: pcie30-avdd0v9 {
       compatible = "regulator-fixed";
       regulator-name = "pcie30_avdd0v9";
       regulator-always-on;
       regulator-boot-on;
       regulator-min-microvolt = <900000>;
       regulator-max-microvolt = <900000>;
       vin-supply = <&vcc3v3_sys>;
};

pcie30_avdd1v8: pcie30-avdd1v8 {
       compatible = "regulator-fixed";
       regulator-name = "pcie30_avdd1v8";
       regulator-always-on;
       regulator-boot-on;
       regulator-min-microvolt = <1800000>;
       regulator-max-microvolt = <1800000>;
       vin-supply = <&vcc3v3_sys>;
};

vcc3v3_pcie: gpio-regulator {
       compatible = "regulator-fixed";
       regulator-name = "vcc3v3_pcie";
       regulator-min-microvolt = <3300000>;
       regulator-max-microvolt = <3300000>;
       enable-active-high;
       gpio = <&gpio0 RK_PD4 GPIO_ACTIVE_HIGH>;
       startup-delay-us = <5000>;
       vin-supply = <&dc_12v>;
};

&pcie30phy {
       status = "okay";
};

&pcie3x2 {
       reset-gpios = <&gpio2 RK_PD6 GPIO_ACTIVE_HIGH>;
       vpcie3v3-supply = <&vcc3v3_pcie>;
       status = "okay";
};

lspci produces no output (literally nothing), even with -vvvv.
Any idea how to debug this?  Thanks.
