sgm4154x int pin must be set as pull up as it will trigger a fall edge signal to interrupt drivers, configure internal pullup resistor to make it work. sgm4154x driver has to enable dpdm regulator to detect the charge type correctly. Once this regulator is enabled, the usb enumeration stop working as the OTG module fails to send signal to dwc3 usb driver, so the dwc3 usb driver has to rely on external extcon to signal the USB cable events, as long as events triggerred, dwc3 usb driver can auto resume the OTG devices, so the enumeration can go on. Set dwc3 work under "otg" mode as it can auto resume the OTG device.
