Cyclone5 SoC: U-Boot not detecting USB-HUB

Hi teiram​ 

I was checking back your usb0 node definition.

usb0: usb@ffb00000 {
compatible = "snps,dwc2";
reg = <0xffb00000 0xffff>;
interrupts = <0 125 4>;
clocks = <&usb_mp_clk>;
clock-names = "otg";
resets = <&rst USB0_RESET>;
reset-names = "dwc2";
phys = <&usbphy0>;
phy-names = "usb2-phy";
status = "disabled";
};

Could you set the status to "okay"? Also, included a few things to try, i.e. increasing the reg size.

&usb0 {
    compatible = "snps,dwc2";
    reg = <0xffb00000 0x10000>;  /* increase the size */
    /* Verify the correct interrupt for your platform */
    interrupts = <0 125 4>; 
    clocks = <&usb_mp_clk>;
    clock-names = "otg";
    resets = <&rst USB0_RESET>;
    reset-names = "dwc2";     /* ensure this matches your reset controller driver */

    /* Key properties for ULPI host */
    dr_mode = "host";
    snps,phy_type = "ulpi";   /* helps older/newer drivers */
    phys = <&usbphy0>;
    phy-names = "usb2-phy";
    snps,dis_u2_susphy_quirk;   /* common with external ULPI PHYs */

    /* Power for the port */
    vbus-supply = <&vbus_5v>;

    /* Pinctrl must be applied */
    pinctrl-names = "default";
    pinctrl-0 = <&usb0_ulpi_pins>;

    status = "okay";
};

As for the vbus_5v and usb0_ulpi_pins definitions, you could refer to this:

vbus_5v: regulator-vbus-5v {
    compatible = "regulator-fixed";
    regulator-name = "vbus-5v";
    regulator-min-microvolt = <5000000>;
    regulator-max-microvolt = <5000000>;

    gpio = <&gpioX Y GPIO_ACTIVE_HIGH>;   /* Replace with your actual GPIO controlling the VBUS switch (if any) */
    enable-active-high;
    regulator-always-on; /* or remove and let runtime handle it */
    status = "okay";
};

&pinctrl {
    usb0_ulpi_pins: usb0-ulpi-pins {
        pins = "...";   /* Replace with your platform’s exact pin/function descriptors */
        function = "usb";
        bias-disable;
        drive-strength = <8>;
        slew-rate = <1>;
    };
};
