Tx2-4g remove vdd-usb2-5v causes usb subsystem to vanish

I removed vdd-usb2-5v from the device tree and all usb went away.

Why did this happen?


Some other usb nodes use it as a vbus regulator. You remove it but the driver still needs a regulator. Thus the driver cannot probe.

If you don’t need those ports on your board, please disable it in DT.

			status = "okay";
			mode = "host";
			vbus-supply = <&vdd_usb2_5v>;
