    32	 * onboard_hub_create_pdevs -- create platform devices for onboard USB hubs
    33	 * @parent_hub	: parent hub to scan for connected onboard hubs
    34	 * @pdev_list	: list of onboard hub platform devices owned by the parent hub
    35	 *
    36	 * Creates a platform device for each supported onboard hub that is connected to
    37	 * the given parent hub. The platform device is in charge of initializing the
    38	 * hub (enable regulators, take the hub out of reset, ...) and can optionally
    39	 * control whether the hub remains powered during system suspend or not.
    40	 *
    41	 * To keep track of the platform devices they are added to a list that is owned
    42	 * by the parent hub.
    43	 *
    44	 * Some background about the logic in this function, which can be a bit hard
    45	 * to follow:
    46	 *
    47	 * Root hubs don't have dedicated device tree nodes, but use the node of their
    48	 * HCD. The primary and secondary HCD are usually represented by a single DT
    49	 * node. That means the root hubs of the primary and secondary HCD share the
    50	 * same device tree node (the HCD node). As a result this function can be called
    51	 * twice with the same DT node for root hubs. We only want to create a single
    52	 * platform device for each physical onboard hub, hence for root hubs the loop
    53	 * is only executed for the root hub of the primary HCD. Since the function
    54	 * scans through all child nodes it still creates pdevs for onboard hubs
    55	 * connected to the root hub of the secondary HCD if needed.
    56	 *
    57	 * Further there must be only one platform device for onboard hubs with a peer
    58	 * hub (the hub is a single physical device). To achieve this two measures are
    59	 * taken: pdevs for onboard hubs with a peer are only created when the function
    60	 * is called on behalf of the parent hub that is connected to the primary HCD
    61	 * (directly or through other hubs). For onboard hubs connected to root hubs
    62	 * the function processes the nodes of both peers. A platform device is only
    63	 * created if the peer hub doesn't have one already.
