	In short, we have three kinds of role switches: - Based on SoC: ID and VBUS - Based on external connnctor, eg, Type-C or GPIO Connector - Based on user choices through sysfs Since HW handling and usb-role-switch handling are at different places, we do not need role_override any more, and this flag could not judge external connector case well. With role_override deleted, We use cdns3_hw_role_switch for the 1st use case, and usb-role-switch for the 2nd and 3rd cases.

2019-08-29	usb: cdns3: Add Cadence USB3 DRD Driver	Pawel Laszczak
	This patch introduce new Cadence USBSS DRD driver to Linux kernel. The Cadence USBSS DRD Controller is a highly configurable IP Core which can be instantiated as Dual-Role Device (DRD), Peripheral Only and Host Only (XHCI)configurations. The current driver has been validated with FPGA platform. We have support for PCIe bus, which is used on FPGA prototyping. The host side of USBSS-DRD controller is compliant with XHCI specification, so it works with standard XHCI Linux driver.
