Wait, why is this text changing?

Add the binding example for the USB3.1 Genesys Logic GL3523 integrates with USB 3.1 Gen 1 Super Speed and USB 2.0 High-Speed hub. For onboard hub controllers that support USB 3.x and USB 2.0 hubs with shared resets and power supplies, this property is used to identify the hubs with which these are shared.
