This series adds support for the role-switch-default-mode binding, to configure
the controller default mode, when the role is USB_ROLE_NONE.
This has been tested on STM32MP15 DK2 board, with:
&usbotg_hs {
phys = <&usbphyc_port1 0>;
phy-names = "usb2-phy";
usb-role-switch;
dr_mode = "peripheral";
role-switch-default-mode = "peripheral";
status = "okay";
}

dt-bindings: usb: document role-switch-default-mode property in dwc2
usb: dwc2: drd: add role-switch-default-node support
usb: dwc2: drd: restore role and overrides upon resume
