About the dual-role architecture, Renesas platform (R-Car H3) has a USB 2.0 host controller (EHCI/OHCI) with OTG function and a separate USB 2.0 peripheral controller (HS-USB). The OTG function is related to some PHY control registers, so I intend to add the OTG/Dual-role core support into the phy driver (drivers/phy/phy-rcar-gen3-usb2.c).
