First, there sure are a lot of controls on a NOP tranceiver. Second, unless Vbus is supplying the PHY, then this belongs in a connector node for which this is already supported. > - reset-gpios: Should specify the GPIO for reset. > > - vbus-detect-gpio: should specify the GPIO detecting a VBus insertion
