We are trying to enable 3 USB3.0 ports on custom board.
I have changed the ODMDATA=0x7090000 to get Config#4 and updated the device tree as below.

usb_cd {
	status = "okay";
	phys = <&tegra_xusb_padctl TEGRA_PADCTL_PHY_UTMI_P(0)>;
	phy-names = "otg-phy";
};

xotg {
	status = "okay";
	phys = <&tegra_xusb_padctl TEGRA_PADCTL_PHY_UTMI_P(0)>;
	phy-names = "otg-usb2";
};

xudc@3550000 {
	status = "okay";
	phys = <&tegra_xusb_padctl TEGRA_PADCTL_PHY_UTMI_P(0)>;
	phy-names = "usb2", "usb3";
	emc-frequency = <150000000>;
};

xhci@3530000 {
	status = "okay";
	phys = <&tegra_xusb_padctl TEGRA_PADCTL_PHY_UTMI_P(0)>,
		<&tegra_xusb_padctl TEGRA_PADCTL_PHY_UTMI_P(1)>,
		<&tegra_xusb_padctl TEGRA_PADCTL_PHY_USB3_P(0)>,
		<&tegra_xusb_padctl TEGRA_PADCTL_PHY_USB3_P(1)>,
		<&tegra_xusb_padctl TEGRA_PADCTL_PHY_USB3_P(2)>;
	phy-names = "utmi-0", "utmi-1", "usb3-0", "usb3-1", "usb3-2";
	nvidia,boost_cpu_freq = <800>;
};

pinctrl@3520000 {
	status = "okay";
	pinctrl-0 = <&tegra_xusb_padctl_pinmux_default>;
	pinctrl-1 = <&vbus_en0_sfio_tristate_state>;
	pinctrl-2 = <&vbus_en1_sfio_tristate_state>;
	pinctrl-3 = <&vbus_en0_sfio_passthrough_state>;
	pinctrl-4 = <&vbus_en1_sfio_passthrough_state>;
	pinctrl-5 = <&vbus_en0_default_state>;
	pinctrl-6 = <&vbus_en1_default_state>;
	pinctrl-names = "default",
		"vbus_en0_sfio_tristate", "vbus_en1_sfio_tristate",
		"vbus_en0_sfio_passthrough", "vbus_en1_sfio_passthrough",
		"vbus_en0_default", "vbus_en1_default";
	tegra_xusb_padctl_pinmux_default: pinmux {
		/* Quill does not support usb3-micro AB */
		usb2-micro-AB {
			nvidia,lanes = "otg-0";
			nvidia,function = "xusb";
			nvidia,port-cap = <TEGRA_PADCTL_PORT_OTG_CAP>;
			nvidia,oc-pin = <0>;
		};
		usb2-std-A-port2 {
			nvidia,lanes = "otg-1";
			nvidia,function = "xusb";
			nvidia,port-cap = <TEGRA_PADCTL_PORT_HOST_ONLY>;
			nvidia,oc-pin = <1>;
		};
		usb3-std-A-port2 {
			nvidia,lanes = "usb3-1";
			nvidia,port-cap = <TEGRA_PADCTL_PORT_HOST_ONLY>;
			nvidia,oc-pin = <1>;
		};

		e3325-usb3-std-A-HS {
			nvidia,lanes = "otg-2";
			nvidia,function = "xusb";
			nvidia,port-cap = <TEGRA_PADCTL_PORT_HOST_ONLY>;
			status = "disabled";
		};

		e3325-usb3-std-A-SS {
			nvidia,lanes = "usb3-0";
			nvidia,port-cap = <TEGRA_PADCTL_PORT_HOST_ONLY>;
			status = "disabled";
		};
		usb3-0 {
			nvidia,lanes = "usb3-0";
			nvidia,function = "xusb";
			nvidia,port-cap = <TEGRA_PADCTL_PORT_OTG_CAP>;
			status = "okay";
		};
		usb3-1 {
			nvidia,lanes = "usb3-1";
			nvidia,function = "xusb";
			nvidia,port-cap = <TEGRA_PADCTL_PORT_HOST_ONLY>;
			status = "okay";
		};
		usb3-2 {
			nvidia,lanes = "usb3-2";
			nvidia,function = "xusb";
			nvidia,port-cap = <TEGRA_PADCTL_PORT_HOST_ONLY>;
			status = "okay";
		};
	};
};

The lane mapping register values are,

nvidia@tegra-ubuntu:~$ sudo busybox devmem 0x02520284 b
[sudo] password for nvidia: 
0x00
nvidia@tegra-ubuntu:~$ sudo busybox devmem 0x02530284 b
0x01
nvidia@tegra-ubuntu:~$ sudo busybox devmem 0x02540284 b
0x01
nvidia@tegra-ubuntu:~$ sudo busybox devmem 0x02550284 b
0x01
nvidia@tegra-ubuntu:~$ sudo busybox devmem 0x02560284 b
0x01
nvidia@tegra-ubuntu:~$ sudo busybox devmem 0x02570284 b
0x02

Only USB3-0 is being detected but not the other two ports.

Please let me know if any other changes are required.
