    Hello, 

    Please find my response below.

    Q1. Yes.

    Q1.1 It means which Power Path VBUS1/2 pin is associated with. Connect VBUS1 to PP1/PP3 and VBUS2 to PP2/PP4 (TPS65988)

    Q2. USB2-only port do not support USB3 signals. Fully-featured port can support all the Type C signal. 

    "Tethered fully-featured cable USB-C plug" Cable which is attached to a device. Example Type C dongles. 

    Receptacle is typically downstream type C port of a Dongle or ports on Notebook.

    Q3. TPS65988/7D is a ROM device. So, it will have ROM code in it at the time of shipment, ROM code cannot be customized. FW patches needs to be applied using external SPI flash. 

     Q4. Registers are not board specific. You can check Host Interface technical reference manual for register details. 

    Thanks
