Ok. You need to specify the type of this property (i.e. that it is a phandle to a syscon node). The description makes it sound like a boolean. > > > > + - mediatek,wakeup-src: 1: ip sleep wakeup mode; 2: line state wakeup > > > + mode; others means don't enable wakeup source of usb > > > > This sounds like configuration rather than a hardware property.

What exactly do you mean by "partial USB ports"? If a phy isn't wired up, it won't be listed in the phys property, if it is then disabling it sounds like a run-time decision.
