arch/mach-meson has some custom usb logic, in particular: * on board_usb_init(), we force USB_DR_MODE_PERIPHERAL * on board_usb_cleanup(), we force USB_DR_MODE_HOST With DM_USB_GADGET=y, board_usb_init/cleanup() are no longer used when we call usb_gadget_initialize(). Instead, the generic (from udc-uclass) initialization/release is called, which itself calls the controller driver's probe()/remove(). Therefore, enabling DM_USB_GADGET=y will mean that this mode switching will break. To prepare for enabling DM_USB_GADGET, perform the mode switching when the "amlogic,meson-g12a-usb" (dwc2) driver is probed()/removed() instead. This is achieved via the glue driver, which gets notified each time one of its children is probed()/removed. Note: this change should be harmless without DM_USB_GADGET=y because the amlogic-g12a-usb driver is not probed via driver model.
