	 * switch from SW to HW control.

	 *

	 * For dr_mode == USB_DR_MODE_OTG:

	 *	if user sets USB_ROLE_HOST or USB_ROLE_DEVICE then driver

	 *	sets role_override flag and forces that role.

	 *	if user sets USB_ROLE_NONE, driver clears role_override and lets

	 *	HW state machine take over.

	 *

	 * For dr_mode != USB_DR_MODE_OTG:

	 *	Assumptions:

	 *	1. Restricted user control between NONE and dr_mode.

	 *	2. Driver doesn't need to rely on role_override flag.

	 *	3. Driver needs to ensure that HW state machine is never called

	 *	   if dr_mode != USB_DR_MODE_OTG.
