    Subject[PATCH 1/2] dt-bindings: usb: add non-removable-ports hub property
    Date
    Add a non-removable-ports property that lists the hardwired downstream
    ports of a hub. Although hubs can provide this information, they are
    not always configured correctly. An alternate means of indicating this
    for built-in USB devices is thus useful.
