Subject: [PATCH 5/8] usb: typec: Use Thunderbolt 3 cable discover mode VDO in Enter_USB message
Date: Mon, 9 Nov 2020 16:37:13 -0800 [thread overview]
Message-ID: <20201110003716.5164-6-utkarsh.h.patel@intel.com> (raw)
In-Reply-To: <20201110003716.5164-1-utkarsh.h.patel@intel.com>
USB4 also uses same cable properties as Thunderbolt 3 so use Thunderbolt 3
cable discover mode VDO to fill details such as active cable plug link
training and cable rounded support.
