This patch adds a property "gpio_usb_connector" which declares a connector child device. Code in the DWC3 driver will then - Search for "gpio_usb_controller" - Do an of_platform_populate() if found This will have the effect of making the declared node a child of the USB controller and will make sure that USB role-switch events detected with the gpio_usb_controller driver propagate into the DWC3 controller code appropriately.
