Description

During the investigation of the issue, was found that the rk3399-rock-pi-4.dtsi file had undergone significant changes, which created a mess in the code during the patch application and unstable pcie operation.

&pcie0 {
ep-gpios = <&gpio4 RK_PD3 GPIO_ACTIVE_HIGH>;
num-lanes = <4>;
max-link-speed = <1>;
pinctrl-names = "default";
pinctrl-0 = <&pcie_clkreqnb_cpm>;
vpcie12v-supply = <&vcc12v_dcin>;
vpcie3v3-supply = <&vcc3v3_pcie>;
status = "okay";
};

&pcie_phy {
status = "okay";
};

&pmu_io_domains {
status = "okay";

pmu1830-supply = <&vcc_3v0>;
};

&pcie_phy {
status = "okay";
};

&pcie0 {
ep-gpios = <&gpio4 RK_PD3 GPIO_ACTIVE_HIGH>;
num-lanes = <4>;
pinctrl-0 = <&pcie_clkreqnb_cpm>;
pinctrl-names = "default";
vpcie0v9-supply = <&vcc_0v9>;
vpcie1v8-supply = <&vcc_1v8>;
vpcie3v3-supply = <&vcc3v3_pcie>;
status = "okay";
};

The patch was put in order and tested on different builds.

How Has This Been Tested?

See full story of the investigation

The kernel 5.15.y works fine in all possible ways boot: cold boot; soft reboot, boot from eMMC when system on eMMC; etc... There are still unstable soft-reboot on the kernel 6.1.y + overlays=pcie-gen2, but this is all better than don't booting at all. And also I think it's can depends on my current hardwere.

  • [x] RockPi 4b v1.5 + remotable eMMC + NVMe KingSpec M.2 NMVe SSD NE 2280 1 TB

Work without any problem:

Sometimes does not define Name when overlays=pcie-gen2 is enabled (only then soft reboot):
