4 Hi-Speed Controller.
7 - compatible : Should be "microchip,usb251xb" or one of the specific types:
11 - reg : I2C address on the selected bus (default is <0x2C>)
14 - reset-gpios : Should specify the gpio for hub reset
15 - vdd-supply : Should specify the phandle to the regulator supplying vdd
16 - skip-config : Skip Hub configuration, but only send the USB-Attach command
17 - vendor-id : Set USB Vendor ID of the hub (16 bit, default is 0x0424)
18 - product-id : Set USB Product ID of the hub (16 bit, default depends on type)
19 - device-id : Set USB Device ID of the hub (16 bit, default is 0x0bb3)
