Don't you need

     vbus-supply = <&vbus0_usb2>;

with vbus0_usb2 a fixed regulator controlled by GPIO P11 (OTG_EXTLPn) from
GPIO expander U11 (TCA9539)?
May be optional, though. salvator-common.dtsi has it.
Yes, I need this gpio.
I need both OTG_EXTLPn and OTG_OFFVBUSn from the same gpio expander.

I've been considering to use either vbus-supply + gpio hog or use gpio hog for both of them for consistency.
What do you think about this?

I plan to add these gpios control as a separate patch.
